----------------------------------------
from <proton/messenger.h>:
{quote}
* The messenger interface is single-threaded. All methods except one
* (::pn_messenger_interrupt()) are intended to be used by one thread
* at a time.

> thread safety issue -- openssl initialization
> ---------------------------------------------
>
> Key: PROTON-787
> URL: https://issues.apache.org/jira/browse/PROTON-787
> Project: Qpid Proton
> Issue Type: Bug
> Components: proton-c
> Affects Versions: 0.8
> Environment: unix
> Reporter: Jim Spring
> Priority: Minor
>
> Doing multiple calls to pn_messenger_subscribe can potentially end up in
> simultaneous calls to pn_ssl_globals_init which calls into openssl which is
> not thread safe.
> One fix is to explicitly serialize calls (my current approach).
> One other fix - allow for an initial "proton_init" type call that includes
> openssl initialization. Which is called before usage of the library.
