+// If no process is waiting for a token when RecycleToken is called, this is a no-op.

+// Since we don't know how many tokens were reserved by the process calling recycle, we will only unblock
+// new reservations that are for one token (otherwise we could recycle a 1-token-reservation and unblock
+// a 100-token-reservation). If all waiting processes are waiting for >1 tokens, this is a no-op.
+//
+// Because recycleCh is an unbuffered channel, the token will be reused for the next waiter as long
+// as there exists a waiter at the time RecycleToken is called. Usually the attempted rate is consistently
+// above or below the limit for a period of time, so if rate limiting is in effect and recycling matters,
+// most likely there will be a waiter. If the actual rate is erratically bouncing to either side of the
+// rate limit AND we perform many recycles, this will drop some recycled tokens.
+// If that situation turns out to be common, we may want to make it a buffered channel instead.

+// Our goal is to ensure that each token in our bucket is used every second, meaning the time between

+//	time_to_recycle * probability_of_recycle * number_of_attempts_per_second <= 1s
+//
+// Therefore, it is also possible for this strategy to be inaccurate if the delay between taking and
+// successfully using a token is greater than one second.
+//
+// Currently, RecycleToken is called when we take a token to attempt a matching task dispatch and
+// then later find out (usually via RPC to History) that the task should not be dispatched.
+// If history rpc takes 10ms --> 100 opportunities for the token to be used that second --> 99% recycle probability is ok.
