Well, output format of "show map" looked different on my system with the
old VM system, but I saw values "ref = 1, nentries = 157, version = 678601"
for the X server.  If 157 is the number I was looking for ;) then it's
higher than 41, but the list is only 4 times as big as yours, so I don't
think it could cause this problem..?
