The event loop tries to run no faster than every 10ms. If it detects
that it goes faster, it would incorrectly calculate the difference, and
then wait (what I assume was) way too long or too short.
Either way, now it's fixed and it correctly works, even when introducing
new lua states.
this gets rid of a bunch of unclear cases which I mistakenly created
while refactoring for this rewrite. One example is having to call into
TTCPServer to do UDP sending in some cases.
