Description

At present, if you invoke fpm on the same project multiple times in parallel, the compiler will trip over itself as it tries to compile the same files at the same time, and can leave the project in an inconsistent state such that subsequent invocations do not try to rebuild when they should. If possible, fpm should avoid trying to build a project multiple times in parallel.

Possible Solution

A quick and dirty solution would be to create a "lock file" on fpm startup and delete it on program shutdown. If the "lock file" is already present, just wait until it's removed. It's not flawless, but could be sufficient.
