added new test case for many tcp connections

It is checked that many tcp connections are properly handled. While
adding this test, I noticed that there is a bug in imtcp that prevents
creation of more than 200 connections. This bug still exists, so the
test suite currently fails (what is correct). Will be addressed soon.
