Oh yes, I'd like to grapple with it, although signalfd() is not directly
available in all libc implementations, e. g. some uClibc versions do not
provide it so need to make a syscall directly (need to roll out
autotools/preprocessor machinery to cater for this).

Also for SIGSEGV (and probably SIGBUS) still need to use the classic
approach (these are some of which signals where originally designed for).

So need to give it a bit of thinking in case of gst-launch. In user apps
it seems to be of less hassle.

Cheers,
Kris
