Adding systemtap probe points in pthread library

[Rayson Ho]

Thanks Roland & Chris for the feedback.

Roland -- I set the mail client to plain text. My first email to this list was blocked by the list, so I will need to find out what needs to be set additionally.

Chris - I will google the uprobes / perf userspace tracing you mentioned. I am currently developing on Fedora 13 with the latest glibc git tree. So I will find out what needs to be upgraded on my machine.

Care to do it so it works with the upstream uprobes / perf userspace
tracing instead of non-mainline code that in this form doesn't have any
chance to be merged?
