Fulcrum v1.9.5: Hotfix Release

"This is a hotfix release. 1.9.4 was a lemon - it contained a bug whereby the server would hang waiting for the mempool (due to inappropriate use of thread variable signals). It has been fixed. I sincerely apologize for the error on my part. All users of 1.9.4 should upgrade to 1.9.5 immediately."
