READ-CHAR-NO-HANG misbehaviour on Windows Console

Bug Description

BUGS #421

It seems that on Windows READ-CHAR-NO-HANG hangs if the user
has pressed a key, but not yet enter (ie. SYSREAD-MAY-BLOCK-P
seems to lie if the OS is buffering input for us on Console.)

This bug hinders SLIME from working correctly with SBCL on Windows.

See for more details.

I hence propose to change the Importance of this bug to High.

Knocking this down to Medium because SLIME has had a workaround for quite a while, and there has been no activity on this in more than a year.
