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. -- Pino Toscano
