Use non-recursive mutexes for c++ qpid::sys::Mutex
--------------------------------------------------
Key: QPID-684
URL: https://issues.apache.org/jira/browse/QPID-684
Project: Qpid
Issue Type: Improvement
Components: C++ Broker, C++ Client
Reporter: Alan Conway
Priority: Minor
Switch qpid::sys::Mutex to use non-recursive mutexes and fix any deadlocks that
result.
We should never be locking recursively and we want to get an obvious
error/deadlock if we do so we can fix the problem.
Recursive mutexes are a Bad Thing, google for the apology by the guy who
invented them if you want to know more. He never intended them to be used for
anything other than as a gross hack for when you had to make thread-unsafe
libraries thread safe but didn't have time to design it properly.
