After this commit, I am seeing parallel queires being stucked on my
windows machine.  I think the notify pid is stale in
ReportBackgroundWorkerExit() as we are freeing the same in
ForgetBackgroundWorker().  Attached patch fixes the problem for me.

Ashutosh Sharma has independently reported (offlist) this problem to me.
