fix Potential stream compression bug

I can confirm this patch. No more zlib errors on our installation (1300 concurrent users).

There are no know confirmations and we are running on pre 3.6.0 OF. How about including it in 3.6.1 beta and go for beta testers confirmation? This bug is only happening in load situations and that would require someone going boldly where no one has gone before (beta installation in production). I think we would go for that 8my team will be upset . . .)

Or Gato is doing his load testing dance again . . . . .

Was this fix tested and confirmed by other people? I would love to send it to MINA devs so they can include it but first I want to confirm that we are in the right path.

assigning against 3.6.1 to get it on the current radar. may get bumped...
