I am listening, but simply have had no luck reproducing ANY problems
in current recently.  I have downgraded my system to small memory
configs, etc...  The last set of bugs that I have fixed were found
when I ran in 6MBytes of mem.  Darn'it the pmap changes are NECESSARY,
but the problems are hard to find... :-(.

I run normally with 6MB/8MB/40MB, and have absolutely NO crashes.  Some laptops
are 486's, and I wonder if somehow we/I have broken compat with those?
