Call me paranoid, but 36 minutes is the time after which a 32 bit
microsecond counter will half-wrap.

So, if you were doing 32 bit calculations from a base time in units
of microseconds then after 36 minutes the calculations will wrap
giving negative results. This might make your system think that it has
to do some work now as opposed to at some time in the future. This
could lead to a busy loop (which will then stop after another 36
minutes).
