Yes, that's right.  It should continue to work back to at least CCL 1.3.

Note that I'm not familiar with usocket---there may well be a better way.

For instance, the patch doesn't set the host-or-ip slot of the condition object to the host or ip address for which the lookup failed.  (In fact, it just sets it to nil for lack of anything better).  

Presumably this won't be an issue since the caller already knows what remote host it tried to connect to.  One other possibility might be to handle ccl:socket-creation-error in get-host-by-address and get-hosts-by-name---that way the address or name would be lexically available to include in the ns-condition object.

Anyway, thanks.  If there are bugs or omissions in CCL that affect usocket (or enhancements to CCL that would make it work better), please feel free to make tickets at http://trac.clozure.com/ccl
