The redifinition of socket-error in acl-compat is causing some
problems. To reproduce, try loading a page in a browser and abort
the load. This triggers a socket error which causes an error to be
thrown like so:
Error in process listener(1): :SITUATION is an invalid initarg to
INITIALIZE-INSTANCE for #<standard-class socket-error="">.
Valid initargs: (:STREAM :ACTION :CODE :
IDENTIFIER).</standard-class>
Removing the definition of socket-error from acl-compat makes
things die differently:
Error in process listener(1): Error on #<TCP-STREAM (SOCKET/6)
