Conflicting signal handlers of octave and qt

[Torsten]

There are several bug reports for the GUI that all seem to be related to
a conflict between the octave and qt signal handler for SIGCHLD
(https://savannah.gnu.org/bugs/?38305, especially comments #36 and #37).
The mentioned issues are fixed by commenting out the line 640 in
sighandlers.cc:

639  #ifdef SIGCHLD
640  octave_set_signal_handler (SIGCHLD, sigchld_handler);
641  #endif

Octave's signal handling is beyond my knowledge. What is the purpose of
the octave SIGCHLD-handler? Is there a chance for omitting the handler
when running the gui?
