[usocket-devel] :timeout NIL for wait-for-input returns immediately on SBCL

[Chaitanya Gupta]

Hi,

On SBCL, providing :timeout NIL to wait-for-input returns immediately 
even when there is no input on any of the provided sockets (the 
documentation says it should wait indefinitely).

Attached is a patch (svn diff) which fixes this, but I am not very sure 
about how sb-unix:unix-fast-select works, so its be best if someone who 
knows better can review it before committing this patch. :)

Cheers,
Chaitanya
