[-- Attachment #1 --] Hi, How do threads interact with signals? In particular, if I have a "main" process thread (the one started by main()) which generates items for a mutex-protected queue which are consumed by a worker thread, and I need to insert an item in the queue from the signal handler, am I correct that doing pthread_mutex_lock() from the signal handler could deadlock if the signal handler is executed by any of the threads (and the mutex is non-recursive)? How is this solved in general? By recursive mutexes?
