Hei Irmen,

I'm not entirely sure what kind of output you need. But here is the
results of running the test cases/benchmarks on my system (Ubuntu
12.04.2 32bits with python 2.7).

=================================================
Indeed it blocks in testPingMessage:

The server gave this error while running (but kept serving):

=========================================
eventloop slow with multiple calls: I don't know how to test.
$ python ./eventloop/client.py
5*11=55
'x'*10=xxxxxxxxxx
press enter to do two more calls:
2*4=8
'@'*3=@@@

(That looked like less than a second, both multiplex and threaded)

===========================================
Just let me know if I can try more things. If you want I can try also to
run it on Ubuntu 13.10 64 bits.

Best,
Éric
