Instance Method Summary
- 
        #after_fork : Nil
        
          no parallelism issues, but let's clean-up anyway 
- 
        #after_fork_before_exec : Nil
        
          reset the mutexes since another thread may have acquired the lock of one event loop, which would prevent closing file descriptors for example. 
- 
        #interrupt : Nil
        
          Tells a blocking run loop to no longer wait for events to activate.

no parallelism issues, but let's clean-up anyway
reset the mutexes since another thread may have acquired the lock of one event loop, which would prevent closing file descriptors for example.
Tells a blocking run loop to no longer wait for events to activate. It may for example enqueue a NOOP event with an immediate (or past) timeout. Having activated an event, the loop shall return, allowing the blocked thread to continue.
Should be a NOOP when the loop isn't running or is running in a nonblocking mode.
NOTE we assume that multiple threads won't run the event loop at the same time in parallel, but this assumption may change in the future!
