Fixed among a ton of other things in v0.14.1.

Introduced Mutex and RecursiveMutex for my upcoming plan to 
rewrite vibe-core on top of photon. Next in line CondVar and with 
that I should be ready to reimplement most of vibe.core.sync.

Also notably I ditched timer based sleeps in favor of a scheduler 
with Mecca's time queue maintained explicitly. Simplified a lot 
of things. I'm uncertain what I'd do about timers so far their 
only API was basically sleep which is already handled by delay. 
That and the coming support for timeout in the select API.

For now it's only Linux and MacOS that have this new scheduler, 
Windows staying mostly as is until around October when I'd 
finally get to my Windows desktop.
