cannot build multiple trees concurrently

[Stewart Smith]

This is a big showstopper for our test infrastructure.

Each machine can have multiple builds going on at once. These are in completely different trees. However, there seems to be a TCP port hard coded as part of the compile as we sometimes get this:

builder_unit_test(["galera/tests/galera_check.passed"], ["galera/tests/galera_check"])

My suggested fix is to instead of hard coding the port, ask the OS to assign you one by binding to port 0 .

Please see my merge request for a true fix for this bug. This bug is a pretty big show-stopper for us, so it would be *really* good if it was merged.

[Alex Yurchenko (ayurchen)]

Stewart, sorry for taking so long - internal miscommunication. The actuall fix would be removal of gu::Network unit from the code, as a first step unit test was disabled. Please retry with r106.
