+##    Commented out these tests because test a non-documented function
+##    (which is actually public, why it's not documented?). Anyway, the
+##    tests *and* the function uses constants in the select module that
+##    are not present in Windows systems (see this thread:
+##    http://mail.python.org/pipermail/python-list/2001-October/109973.html)
+##    Note even that these constants are mentioned in the select
+##    documentation, as a parameter of "poll" method "register", but are
+##    not explicit declared as constants of the module.
