Correct, the mutexname isn't allowed to have slash's in it

Probably correct too.

But currently we are at the stage that the SSLMutex passes a NULL 
filename in for the mutexname and assumes the apr will generate

server/mpm/winnt/mpm_winnt.c however does pass in a NULL filename
and wishes to get NULL-filename mutex (ie. a private mutex).
So a autogenerated filename from apr will probably break this
