There are pure python alternative implementations of these protocols and of mysql, anything pure python works well, but of course there are modest CPU costs. Then there are workarounds if you must use C libraries with blocking IO, like using a pool of sub-processes. But using C libraries for IO is pretty low level stuff, and making them concurrent is beyond the scope of python.
