1650, manythreads.exp, works every time with gdb 6.1.1.
So if there's a kernel race condition then gdb does not trigger it
and gdb HEAD does.  This is a user-visible regression.

BTW, I did try to reproduce this bug. Mainline GDB and manythreads.exp appear to work everytime on NPTL based FC2 and RHEL2 GNU/Linux systems (well at least for the 30+ test runs I tried). That wasn't the case with 6.1.

We should probably mention this fix in the NEWS file, and the apparent linuxthreads regression in PROBLEMS.
