              * SigQ: This field contains two slash-separated numbers that
                relate to queued signals for the real user ID of this
                process.  The first of these is the number of currently
                queued signals for this real user ID, and the second is the
                resource limit on the number of queued signals for this
                process (see the description of RLIMIT_SIGPENDING in
                getrlimit(2)).

USER - wlasciciel
       pid         PID       a number representing the process ID (alias tgid).
       pgid        PGID      process group ID or, equivalently, the process ID of the
                             process group leader.  (alias pgrp).
       tid         TID       the unique number representing a dispatchable entity
                             (alias lwp, spid).  This value may also appear as: a
                             process ID (pid); a process group ID (pgrp); a session ID
                             for the session leader (sid); a thread group ID for the
                             thread group leader (tgid); and a tty process group ID for
                             the process group leader (tpgid).
       pri         PRI       priority of the process.  Higher number means lower
                             priority.
       stat        STAT      multi-character process state.  See section PROCESS STATE
                             CODES for the different values meaning.  See also
                             s and state if you just want the first character
                             displayed.
       wchan       WCHAN     name of the kernel function in which the process is
                             sleeping, a "-" if the process is running, or a "*" if the
                             process is multi-threaded and ps is not displaying
                             threads.
       ppid        PPID      parent process ID.

PROCESS STATE CODES
       Here are the different values that the s, stat and state output specifiers
       (header "STAT" or "S") will display to describe the state of a process:

               D    uninterruptible sleep (usually IO)
               I    Idle kernel thread
               R    running or runnable (on run queue)
               S    interruptible sleep (waiting for an event to complete)
               T    stopped by job control signal
               t    stopped by debugger during the tracing
               W    paging (not valid since the 2.6.xx kernel)
               X    dead (should never be seen)
               Z    defunct ("zombie") process, terminated but not reaped by its parent

       For BSD formats and when the stat keyword is used, additional characters may be
       displayed:

               <    high-priority (not nice to other users)
               N    low-priority (nice to other users)
               L    has pages locked into memory (for real-time and custom IO)
               s    is a session leader
               l    is multi-threaded (using CLONE_THREAD, like NPTL pthreads do)
               +    is in the foreground process group
