I have not found this to be a problem; in both DJGPP and TC++, getch()
seems to remove one character from the keyboard buffer and thereby
turns off kbhit().  There may well be trouble if one /holds down/ a
key, which is why I usually put a loop like this

while (kbhit()) getch();

in critical locations, but a single keypress should be fine.  I
suspect the trouble stems from some other part of the code.
