r1679032:

mod_ssl OCSP Stapling: Don't block initial handshakes while refreshing
the OCSP response for a different certificate.  mod_ssl has an additional
global mutex, "ssl-stapling-refresh".

Not mentioned in CHANGES:

Stapling no longer uses a mutex when using a stapling cache
implementation which doesn't require it.  (A further, unrelated
code change to mod_ssl is required to allow the use of memcache 
as a stapling cache, and I haven't tested with distcache; thus
it isn't clear if this helps in practice yet.)
