folks, I'm having an issue while using gwlib. Under heavy load under multi CPU systems (intel and powerpc), We're seeing the error "mutex_lock: Managed to lock the mutex twice!" The issue is that it is being called by a normal debug() statement. The only mutex lock generated in debug() is gwlist_lock(writers) and I have so far not been able to figure out any theoretical scenario where this could occur except when debug would call debug again but this can not happen. It can call panic under some rare scenario which would then lock again but we already fixed that by having panic not considering locking writers (there's no point as we will exit afterwards immediately anyway). Anyone have a hint?
