However, it seems the book is talking about linuxthreads by Xavier Leroy, not nptl. I am well aware that linuxthreads uses LWP's to implement threads and as a result, each thread has a separate, unique pid. I did a few more tests using gdb and my simple app. I am seeing the SIG32 signal and the lack of the manager threads. So everything hints that I am indeed using nptl, but the separate process id's still doesn't make sense... -- Timur
