Darn it!

You are absolutely correct, /tmp was on /, ext3 builtin, ext2 as module, so 
it was really still ext3. /bin/mount lied to me. When I moved /tmp to its own 
partition, really ext2 this time, things stopped misbehaving. That ext2/ext3 
thing was the very first thing I tried, wasted a lot of time :-(

I could certainly believe that the (weird) ext3 behaviour would upset
the overcommit beancounting though.  Hundreds of megabytes of memory
on the inactive list but not in pagecache probably looks like anonymous
memory to the overcommit logic.

Does this bit mean the report was still somewhat useful (for fixing either 
ext3 or the overcommit accounting) though, or was it already well-known?

Well, anyways, thanks heaps for the explanation, was going slowly mad here ...
