> In high load situations, with a NO_ACKNOWLEDGE session, it is possible for 
> the client to create an excessive amount of threads to suspend/resume the 
> channel.
> I'm providing a patch to avoid creating a new thread if the previous thread 
> has not completed its operation. This patch appears to avoid the problem in 
> our environment. Notice we are using version 0.24, but the code is the same 
> in the latest version.
