Adam Jackson 137ac094e7 dix: Push UpdateCurrentTimeIf down out of the main loop 
This was added in:

        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.
