Title: Fix race condition between release_machine and @reactor_running

Code gated on EM.reactor_running? will cause a RuntimeError to be
thrown if executed *after* a call to release_machine() but *before*
@reactor_running is set to false. A prime example of this is code
executed in a signal handler.
