Subject concurrent ssl context access
Date Mon, 11 Jul 2016 10:25:19 GMT
In https://bz.apache.org/bugzilla/show_bug.cgi?id=59840 the issue crept up that StdEnvVars
makes concurrent access to the SSL context when HTTP/2 is in place. 

The question is: how do we want to fix this?

The general theme is that a module needs to perform some action on a connection, sees that
it is a slave connection and accesses the master instead. Such a module needs to be aware
that access to master may happen in parallel with other request.

Should we let each such module care for it on its own or do we want to provide a way to access
the master connection in a mutex protected way?
