HEAD is hanging quite frequently...
I'm seeing frequent occurrences of slapd getting stuck during trivial
operations; this is, for example, test003. The problem is quite
repeatable, although some times it hangs in a slightly different place.
I haven't been able to complete it in tens of attempts, though.

I note those strange messages about connection_read (no writing seems to
be occurring at all, during this test).
The software/hardware is a CentOS 4.2 (RehHat AS4 clone) running on
AMD64.
Any clues? I'm not submitting an ITS yet because i suspect something
trivial on my side.
