[Octave-patch-tracker] [patch #7949] octave-gui freezes for 30+ seconds when trying to display a new documentation tab

[Andre da Costa Barros]

Follow-up Comment #2, patch #7949 (project octave):

I have new patches versions that improves the situation a bit but, from what I
gathered about the source of the problem, it comes from the way QProcess
handle signals on unix. I am kind of playing wait-and-see as Qt 5.1 is close
to be released and I am not sure if the effort to correct the problem, like
what vlc team did, is worth the time spending.

Also, I am not sure when it happened, but the destructor is working fine now
so, I guess, whatever was killing the octave process before all cleaning code
could be triggered it is gone now. The bad side of it is that octave starts a
bit slower now that it has to generate the temporary files at startup.
Perhaps, I will change the code and leave the temporaries alone. ;-)

Besides all that, the documentation is working fine (no delays) inside KDE for
me and the qt interface is really nice to work with.

It should be noted that the problem with QFileDialog is also related to this
it seems (again, QProcess).
