leak tracer: signal handlers need fixing
Submitted by Tim Müller @tpm

Description
The signal handlers in the leaks tracer need fixing up.
You're not really allowed to do anything meaningful in a signal handler, so it works at all, that's mostly luck.
Probably needs to be rewritten using another thread and/or signalfd() or GLib's signalfd wrapper source thingy.
