    Great! Where does this leave NGPT though? I had assumed that
    this was going to be the next pthread implementation in glibc.

    Subject: glibc threading performance

    Hey guys,

    I noticed you're looking at threading stuff lately,
    and was wondering about this thread:

    In summary wouldn't it be better to have a per process
    flag that was only set when pthread_create() is called.
    If the flag is not set, then you don't need to do locking.
    This locking seems to have huge overhead. For e.g. I
    patched uniq in textutils to use getc_unlocked() rather
    than getc() and got a 300% performance increase!
