Simultaneous builds of the same source trees (via ant's parallel task) will often result in an instance of devenv.exe hanging/spinning (consuming ~24% CPU).

The entire build consists of many C++ projects. More often than not, the build of the first project is the one that hangs.

Hello, and thank you for the feedback. Parallel builds of the same source using custom tasks such as Ant’s Parallel task is not a scenario supported by MSBuild. Apache Ant's Parallel Task documentation (http://ant.apache.org/manual/Tasks/parallel.html) specifically warns against that sort of usage as it must be explicitly supported by the tasks to be run in parallel.
