Threads Signals

Hi

In my process there are few threads. Now, lets say all the threads are blocked for some reason or other..

now i read it somewhere that the kernel in this situation sends in some signal which can be caught.

please let me know what signal is it and more details about that..

Thanks in advance.

Though I have never worked at such a core level in thread programming but my understanding is that when the kernel realizes that all of a process's LWPs are blocked at the kernel level, it drops a SIGWAITING on the process.
