[cmake-developers] CMake 3.4.0-rc2 ctest hangs with 100% CPU

[Nils Gladitz]

I switched from 3.2.1 to 3.4.0-rc2 on a Windows and a Linux dashboard 
client for a custom project.

On the Linux client parallel testing now loops with 100% CPU somewhere 
in cmCTestMultiProcessHandler::StartNextTests and 
cmCTestMultiProcessHandler::CheckOutput.

I don't have a proper stack trace on the windows client but it seems to 
hang there too.
