Update currentTime in dispatch loop
Unfortunately this is equivalent to calling GetTimeInMillis() once per
request. In the absolute best case (as on Linux) you're only hitting the
vDSO; on other platforms that's a syscall. Either way it puts a pretty
hard ceiling on request throughput.
Instead, push the call down to the requests that need it; basically,
grab processing and event generation.
