Subject: [PATCH] Disable mid-tick task execution

Mid-tick task execution acquires the ticket lock at least,
which can possibly be a significant performance bottleneck
at a high tick thread + region count. This change should reduce
the impact from scaling the region threads, but is not a fix
to the underlying issue.
