SIGURG

[Matthew George]

I have a fairly active program that forks and uses pipes to communicate
back to the parent before exiting.  When I go to wait() on the child,
occasionally the status is signaled - SIGURG instead of exit()ing
normally.  It appears the child process is doing everything it needs to be
doing.

What will generate this signal?
Is it safe to ignore, or should I be handling it somehow?

This is running on 4.10 ...
