Bigloo GC and SIGINT

I've noticed in my work with Bigloo that sometimes when a process running from the REPL is sent SIGINT (C-c), the GC hangs in the function GC_lock. I don't know if it's related to dynamic-load-ing on OS X, or whether this is a general problem, and the GC is not very resistant to SIGINT. I suppose it could also be my optimization options on the compiled C code (I'm optimizing pretty heavily for my numerical work). I'm just putting it down here so I don't forget to file a bug report if I ever figure out the cause.
