20 us was the value, firefox used as first response to the spectre attacks.
now it's 100 us or 5 us, depending on whether it's "cross-origin isolated".
we only have one origin, so choosing 20 us is probably fine, I guess

other clocks:
* os.time() and os.date() only have seconds precision, AFAIK.
* dtime is only given once per step, so it's not useful
* there might be other ways to build clocks (if we get async envs for sscsm,
with a busy loop, for example)
* Network: offload often changed constants to source file
This prevents unnecessary recompiling when using incremental builds.
There is also no need to have separate max proto version variables;
as they're subject to the handshake between client and server. The
code is also expected to support the same version (or higher).
