Do you think it's feasible to modify Python to use non-blocking i/o
everywhere, and then simulate blocking in Stackless?  I.e. when a
microthread does an i/o operation, Python would start the operation
asynchronously, and the Stackless microthread scheduler would block
the microthread til the i/o operation actually completes (detected
using select or SIGIO).
