Start of History.md for 0.9.0.1
  Fix for SIGUSR2 signals during startup.

  There was a rare race condition where SIGUSR2 can fire before the
  server starts listening, causing some functions to fail. We added
  a future to the synchronous queue to ensure that SIGUSR2 calls
  are queued to run after onListen.

Spiderable now uses a flag to determine when the initial JS has loaded

Other approaches seemed to be heuristics that broke down in edge cases:
a timeout wasn't guaranteed if your JS was slow; page.load in PhantomJS
wasn't firing reliably because of long polling.
