*
* This implementation sets a thread-specific flag on entering wait()
* that indicates that the thread is unavailable to service upcalls.
* Connection handler that are acting in a server role cooperate by
* checking this flag in their handle_input, and returning if they're
* in a thread that is currently suspending upcalls. The flag gets
* reset once the reply is received.
