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 cachek, and I haven't tested with distcache; thus
it isn't clear if this helps in practice yet.)

This saves unnecessary socket pool destroy and creation at cleanup and reuse
time, plus the same initialization of conn->pool's associated data which can
be reused in that case.
