What signals does Blender respond to? By "signals" I mean the age-old unix signals like SIGSTOP, SIGQUIT, SIGPWR, SIGALRM, SIGUSR1, etc.

Which ones does the Blender process not ignore, and how does it react to each?    I'm curious about signals sent to Blender by the operating system, user, or other software.

I don't recall seeing mention anywhere in any documentation.
Here are the signals Blender currently uses.


SIGINT (Ctrl+C in the terminal) is used to cancel renders.
SIGFPE can be enabled by passing --debug-fpe to Blender, we use the for finding errors while debugging.
SIGSEGV writes a crash log in the temp directory, unless --disable-crash-handler argument is passed.
