So if I call WAIT-FOR-INPUT on a usocket instance with no TIMEOUT keyword supply, (TRUNCATE NIL) will be called, and error happens. How to fix this issue to make sure I can just wait "infinitely" on a usocket?
Not having tried it, but (and timeout (truncate timeout)) should do, no?
I don't think so.
MP:PROCESS-WAIT-WITH-TIMEOUT must be called with a TIMEOUT parameter as integer (in seconds). If TIMEOUT is NIL, WAIT-FOR-INPUT-INTERNAL maybe should turn to call MP:PROCESS-WAIT instead of MP:PROCESS-WAIT- WITH-TIMEOUT:

I made a patch based on above idea, as in attach, it works under simple test.
