Simple threaded web-server based on BaseHTTPServer?

Right, that's the attraction -- small memory burden, very fast context
switches, and as many microthreads as you want (limited only by available
heap space).

Also right.

Well, because there aren't "real threads" under the covers, a blocking
operation in one uthread blocks *all* uthreads for the duration.

It should be possible to combine uthreads w/ native threads, but the
semantic model gets ever-harder to master the more gimmicks get tossed into
the mix.
