This doesn't add full support. Doing so requires cooperation from the
libraries. However, this does solve the case where a request is
cancelled, we don't block and return control to the caller. The
consequence is that we're leaking a goroutine for the remainder of the
open request to memcache/redis (which shouldn't be long)
Both libraries expose the ability to set timeouts on connections. It
might be worthwhile to see how to integrate them more seamlessly:
