* Fix to race condition where file descriptor copies were being made at

  sequences to validate that things don't break down with either lots of

* Change minimum debugging level to -1 to allow suppressing logging
* Bug 92 - compression of event numbers had a bug where events >
  2^31-1 would overflow the "int" value
