Message:

Mutex for DBM cache access

I noticed that with a DBM cache enabled and session tickets disabled
even a handful of parallel connections trashed the cache database, and
consequently the error log. According to comments and documentation on
mod_socache_dbm the APR DBM module is not thread or multi-process
safe, so a global mutex is necessary. With the mutex the cache
corruption disappears in my benchmarks.
