2- memory considerations on coroutines. Beside coroutines allow more
readable code I wonder if somebody considered memory. For every
coroutines a different stack has to be allocated. For instance
ucontext and win32 implementation use 4mb. Assuming 128 concurrent AIO
this require about 512mb of ram (mostly only committed but not used
and coroutines are reused).
128 concurrent requests is a lot. And even then, it's only virtual
memory. I doubt that we're actually using much more than we do in the
old code with the AIOCBs (which will disappear and become local
variables when we complete the conversion).
