GSCreator: Fix hang due to calling exit() after fork()
Summary:
After fork(), exit() invokes atexit handlers, which can result in a lockup if
an atexit handler uses thread synchronization facilities, since all but the
current thread no longer exist. An example backtrace can be found in the linked
bug report. Fix it by using _exit() instead of exit().
FIXED-IN: 20.03.80
Test Plan: I don't know the exact environment required to trigger this bug, but
one precondition is to trigger generation of thumbnails via this code; maybe
browsing folders with PDF files will do that. Once you see thumbnail.so
processes staying around, you must have hit this bug. This patch should prevent
this issue from occurring, and it did on my system.
