Returns an estimate of the total number of tasks stolen from
one thread's work queue by another. The reported value
underestimates the actual total number of steals when the pool
is not quiescent. This value may be useful for monitoring and
tuning fork/join programs: in general, steal counts should be
high enough to keep threads busy, but low enough to avoid
overhead and contention across threads.

@return the number of steals
