Ok, here's some news, in case they can be of some interest.
I managed to write an asyncore disptacher which seems to work.
I used my test suite against it and 70 tests passed and 2 failed.
The tests failed because at a certain point a call to do_handhsake
results in an EOF exception, which is very strange since it is
supposed to raise SSL_ERROR_WANT_READ or SSL_ERROR_WANT_WRITE only.
I'll keep you updated in case I have some news.
--- Exception ---
