If you send "too many" messages to netsend in zero logical time, PD immediately stops responding forever, WITHOUT eating up any cpu at all.
Attached patch illustrate the problem.
Click on the "connect" message box, and then on the [bng]
Note that it only happens if netsend is connected. If not connected, it will properly output all the "error: not connected" error messages.
Tested on Windows XP, Intel Core Duo.
