You're not going to get anyone to spend a minute trying to figure what's happening on virtual hardware with an ancient version of PostgreSQL. If this was an actual full test case against PostgreSQL 8.4 or later on a physical machine, it might be possible to draw some conclusions about it that impact current PostgreSQL development. Note where 8.1 is on http://wiki.postgresql.org/wiki/PostgreSQL_Release_Support_Policy for example.
