* sleep handled the full range of integers, that's why, and a
* double can't handle a large long. This is fairly useless
* given how large a number a double can hold on most
* machines, but now we won't ever have trouble. If you want
* 1000000000.9 seconds of sleep, well, that's your
* problem. Why use an isdigit() check instead of checking for
* a period? Because doing it this way means locales will be
* handled transparently by the atof code.
