Most important, I think, is for non-reactor code to not block. E.g. if
you're using a library to read from a database, the database library code
should release control between the time you make a request and the time the
library delivers the results of that request. For example, a "nice" request
call might have a callback argument and return immediately, triggering the
callback when results are ready.
Note that if you *must* use a library which is blocking, a possible solution
is to execute the blocking code in a thread. But, this isn't easy to get
right and the python GIL can cause problems if you need a lot of threads.
