The test wasn't as robust as expected.
Change the way we verify that we are having a un-blocking compilation:
First lock the compilation queue - no new compiles will be completed.
Enqueue method for compilation. If the method is compiled blockingly -
the java thread will hang since the compile can't complete as long as
the compile queue is locked.
Use this to test the blocking functionality in three steps:
1) Verify that we are not blocking on target method as described.
2) Add compiler directive with instruction to block on target method -
verify that it can be compiled on all levels. If it is not blocking it
will eventually be stalled for a moment in the compiler queue and the
test will fail.
3) Pop directive, and redo step one - verify that target method is not
