But on another XP of mine the call to make-socket goes away for almost a

socket:make-socket resolves :remote-host using socket:lookup-hostname.
Try evaluating (socket:lookup-hostname "s3.amazonaws.com") to see if this
is the cause of the timeout.
If it is, you can fiddle with socket:*dns-mode*, which on 8.1 defaults to
'(:ACLDNS :CLIB) which means that it first tries to query using its CL-
only resolver, using the system C resolver as backup. It may be that
Allegro's resolver has a bug so you could try to set *dns-mode* to
'(:clib :acldns) and retry. If both resolvers time out, it may be that
something on your computer(perhaps your firewall) or upstream is blocking
UDP queries - the DNS protocol says that a resolver should first try UDP,
than TCP when querying a server.
