    Subjectthread groups bug?
    Date
    From

    Hi Linus,

    If the master thread of a thread group (PID==TGID) performs an execve() then
    it is possible to end up with two or more thread groups with the same TGID.

    Would you be willing to have an execve() on the master thread kill all the
    other threads? (And thus be slightly closer to POSIX compliance).

    Similarly, if the master thread exits, should all the other threads be killed
    too?

    If a subsidary thread does an execve(), then what should happen? I can see two
    ways of handling it: (1) Make it seem that the master thread did an execve(),
    and kill all the other threads (which is closer to POSIX); and (2) allow the
    child thread to depart the thread group and set up by itself (as happens now).

    Of course, comparing Linux thread groups to POSIX threads doesn't hold up very
    well:-)
