WIP: threadpool: token-based sequencing
Here's a reaaaaally rough implementation of token-based sequencing for
util/threadpool. The idea is to allow multiple contexts to share a single
threadpool with a high number of threads while also ensuring that the pool
executes tasks belonging to each context in order. Previously this was only
achievable via one-singleton-threadpool-per-context, which grossly inflates
the total number of threads.
WIP because it's incomplete, is poorly documented, needs a lot more tests,
is suboptimal from an allocation perspective (too much map access?) and is
probably outright broken.
