4.0.0

BREAKING CHANGE: Since version 4.0, the client longer polls for network events
at shutdown (during object destructor). This behaviour didn't give enought
control to the user in case of server issue, and could cause the script to
hang while terminating.

Starting from this version, programs MUST now call flush() before shutting
down, otherwise some messages and callbacks may be lost.
