+ * xnanosleep.c (timespec_subtract): Don't modify the 2nd arg.
+ Work even if X-Y overflows when subtracting. Make explicit the
+ assumption that tv_nsec must be in range.
+ (clock_get_realtime): Remove. All callers changed to invoke gettime,
+ for simplicity.
+ (xnanosleep): Check for gettime failure every time.
