Description of problem:

Using the proton-c reactor: on reconnect the reactor may stop responding to wake up requests from other threads (via pn_reactor_wakeup())

This manifests as the reactor thread failing to respond, or responding slowly if a periodic timer is used.  pn_reactor_wakeup() also returns an error code every time it is called.

Version-Release number of selected component (if applicable):

qpid-proton-c.0.11.1

How reproducible:

100%

Steps to Reproduce:

See reproducer attached to upstream JIRA.

Actual results:

Reactor thread does not respond immediately to wake up requests from the foreground thread.  The wakeup is not processed until the reactor timer expires. pn_reactor_wakeup() returns an error code.

Expected results:

Reactor should wake up immediately in response to the pn_reactor_wakeup call.
pn_reactor_wakeup() returns a success code.
