LDT initialization after fork() for LinuxThreads?

[Wolfram Gloger]

Hi,

Maybe I'm missing something obvious, or I just don't understand the
LDT stuff sufficiently.

But, my tests indicate that modified LDT entries aren't inherited
across fork().  So, aren't we missing something like the untested
patch below, since __pthread_reset_main_thread() doesn't do any
INIT_THREAD_SELF?

Regards,
Wolfram.
