Testcases in this directory require zzuf and socat.

zzuf is used to randomly mess with the TCP connection between the CURL
clients and the MHD server.  The goal is to expose problems in MHD's
error handling (by introducing random syntax errors).  socat is
used to listen on port 11081 and forward the randomzied stream to
port 11080 where MHD is waiting.

As a result, the testcases in this directory do NOT check that
whatever CURL returns is what was expected -- random modifications to
the TCP stream can have random effects ;-).  Testcases "fail" if the
code crashes or hangs indefinitely.
