Something is wrong here. It should use 20 connections at maximum. Maybe connections cached by the OS during close count against the ulimit as well?
Note that there are some tests that explicitly use many connections -- because that is what they test. manyptcp.sh is a sample of this. In any case, I'll add a valgrind test for imptcp_conndrop.sh, so that we can see if there is an actual leak. That would be an explanation.
