Problems with X server

[readingj@CERF.NET (John D. Reading)]

I just went to connect to a remote host using the X server program
on the Symbolics, and got a "divide by 0" error. "That's strange", I
thought. So I went and looked at the routine that was giving the
error. It was supposed to return the time in milliseconds. Predictably
enough, it gets the full-microsecond-time, then calls some undocumented
function to divide the two-part number thus obtained by 1000. After a 
little fiddling I realized that full-microsecond-time has just very
recently (probably today?) clicked over to 1000 in the high value it
is returning. I tried using (mod high 1000) in the routine as an
argument to the undocumented function, and it worked just fine.

Question: Is everybody else having this problem today, or is it only
me? Does anybody have a better solution than mine? The actual function
being called by X is x-server:|GetTimeInMillis|, and the function
getting the error is sys:%divide-bignum-step (for which I don't have
the source, so I have no idea how to fix it).

Thanks one and all;
