This seems like something that must have a well-known solution, but I haven't dug it up yet. 
I'm working on an app talking to a network attached device. I want to allow multiple threads to send requests to the device, and have another thread that blocks waiting for responses to come back.  There could be multiple outstanding requests, and there's no reason from my code's perspective that responses should come back in order.
My initial attempt uses pasynOctetSyncIO->write and pasynOctetSyncIO->read, but it looks like there's a mutex in asynOctetSyncIO writeIt and readIt functions that prevents writing while read is blocking. Is there a way to allow the "reading" thread to wait for responses that still allows writes to happen?

Thanks,
Garth
