I just compiled LDMud, and noticed there were actually few other efuns
I had hacked into Amylaar GD... Some aren't probably useful for anyone
else out there, but others might be. Although I don't want to add yet
another dozen of esoteric efuns to GD, I think it'd be good to discuss
about possible useful new additions anyway. So, here's my list:

- query_micros(); for performance optimizations I wrote a simple efun
  that returns a microsecond-resolution counter. It is of course affected
  by all kinds of overhead from OS scheduling to whatnot, but in any case
  it makes performance optimizations easier:

  #ifdef F_QUERY_MICROS
    CASE(F_QUERY_MICROS);
    {
	int i;
	struct timeval tv;
	gettimeofday(&tv, 0);
	i = tv.tv_usec % 1000000;
	push_number(i);
	break;
    }
  #endif

  If time() returned to the millisecond or microsecond resolution, that
would be more than sufficient.  I remember that Genocide had to add in a
hack so that time could be reported in hundredths of seconds...
