Hello,

    I am writing a program which sproc's a child process for network and
file i/o. The child seems to run faster when I use the PR_NOLIBC flag
(a factor of 5 on our old Power Series machines). The performance decrease
seems to be due to semaphore locking and unlocking. Does using this flag
have any bad effects other than making errno unreliable? I'm using Performer
1.2, IRIX 5.3 on a variety of platforms.
