Acquires a lock on the project build path and runs the given function.

When another process (across all OS processes) is holding the lock,
a message is printed and this call blocks until the lock is acquired.
This function can also be called if this process already has the
lock. In such case the function is executed immediately.

This lock is primarily useful for compiler tasks that alter the build
artifacts to avoid conflicts with a concurrent compilation.
