In some contrived case, it might theoretically be the case that
destroy is called from another thread, which would modify the
threads array from two threads.

Avoids a DB error (leading to an assert) where a thread uses
a read txn previously created with an environment that was
since closed and reopened. While this usually works since
BlockchainLMDB renews txns if it detects the environment has
changed, this will not work if objects end up being allocated
at the same address as the previous instance, leading to stale
data usage.
Thanks hyc for the LMDB debugging.

use unsigned int to avoid having to range check negative numbers,
use const where possible, don't needlessly create empty objects,
use std::move where possible
If an exception is thrown, it is ignored. While this may hide
a bug, this should only be system exceptions in boost, which
is pretty unlikely. Morever, wait should be called manually
before the dtor anyway. Add an error message if the dtor has
to wait in case some such cases creep in so they get fixed.

If a queued job uses a waiter, then we want to run that waiter's
jobs in the current thread if all threads are busy, even if the
queue is empty, since there is no guarantee that any thread will
free up to take care of that new job, since all the threads might
be running a job which spawns such a recursive job and will block
till that recursive job is done, which it will never be since it
relies on the queue being polled by one of those blocked threads.
