Description: Fixes lockups when signals arrive.
Details: the return value of -1 from select() that propagates into flag means 
that it was interrupted by a signal. In this case, at least with glibc 
from trunk (2.3.90), the return value from FD_ISSET is undefined. Thus, 
GET(win) can be called when there's no actual input. This results in the 
lockup until a key is pressed.
