Description

There seems to be a problem with file locking, double lock does not wait for acquiring but fails on the write itself:

The problem seems to be the way windows locks work in fs2

Possible solution:

1. Aquire global lock on the cache file when starting forge
2. Handle reading and writing either by using rust mutex/lock/similar mechanism or some intermediate, in-memory structure that is dumped to the cache file at the end of the execution
3. Release global lock on the cache file when forge finishes executing all tests
