You can see in the Rebel board that the problem of infinite time is known.

I found the problem when I analyzed a position for a long time.

My experience is that the time is dependent on the position and I had examples
when the time was less than 3 hours on my PIII450(192 mbyte hash)

I had also an example when the time per move was more than 6 hours and in this
case I did not try to check if the inifinite is finite.
