> The recent changes to Apache.NMS.ActiveMQ's file OpenWire/OpenWireFormat.cs create massive
delays on my system. If I revert that file back to the version 693666 (09-Sep-2008) then all
my code starts working without delays. It seems that the action of writing to the bus (using
Topics in my case) is delayed 120 seconds or so. Each write seems to be delayed 15 seconds.
Since startup involves several writes the initialize the wire format, I suspect that a timeout
variable is set to 0 (zero) which does not allow a thread-swap to take place. I suspect that
the timeout should be set to 1 ms so that a context switch will take place.
