I find that shocking. The patch only populates ppid and ptid with a 
value read from the file that is already opened and processed. Most of 
the patch is just plumbing the value from the low level function that 
processes the status file back to synthesize_fork.

What benchmark is this? Is it something I can download and run? if so, 
details? site, command, args?

Thanks,
David
