I remember reading a request from Linus Torvalds on lkml that the kernel support for threads that NPTL would use should not treat any thread of a process differently to any other, so any threads can die, and any one of them can be the last. I meant that I thought a thread doesn't become the parent of one that it creates (that they both have the same parent - the process that was the parent of the first one). I admit I don't know the details. -- Tristan Wibberley Opinions expressed are my own and do not necessarily coincide with those of my employer, etc. -- Kernelnewbies: Help each other learn about the Linux kernel.
