Agreed, the configuration workaround is viable; but the problem lies
in the actual troubleshooting. Coming to this conclusion takes time,
time the users don't have when the workers are crashing. Its not always
possible to rollback the configuration or understanding right away what
particularity caused the crash (after a move of vhosts from one server to
another for example).

So perhaps until a proper fix is ready, we can add a note in the documentation:
http://nginx.org/en/docs/http/ngx_http_ssl_module.html#ssl_session_cache


Its not about the workaround, its about knowing such issues and limitations
in advance.
