Title: Initialize BlockContext thread local to null to avoid a leak

Generally considered bad to have an initialValue that points to something we might want to GC.

This doesn't change public API behavior in any known-detectable way, other than potentially allowing more stuff to GC without shutting down the thread.

Review by @phaller or @axel22 for example.
