libgc doesn't uses SIGUSR1 everywhere, just on FreeBSD (not kFreeBSD) 
and on Hurd. Everywhere else it uses SIGRTMIN + 5 & SIGRTMIN + 6.

What ecl could do is check whether there's a signal handler already set 
for DEFAULT_THREAD_INTERRUPT_SIGNAL, and try again with other signal(s). 
Although, this still wouldn't help if ecl would first set the signal 
handler, and then libgc would do the same.
