SubjectPID of multi-threaded core's file name is wrong in 2.5.59
Hi,

I found sometimes pid of muitl-threaded core's file name shows
wrong number in 2.5.59 with NPTL-0.17. Problem is, pid of core file
name comes from currnet->pid, but I think it should be current->tgid.

Following patch fixes this problem.
