8.0.0 gmake check fails if on disk, passes on ram disk....

Hi,

If I put the source for 8.0.0 on disk (RAID 1) , configure, compile and 
run gmake check, it fails with 33 errors, 30 of which are

! psql: could not send startup packet: Broken pipe

If I put the same source code up on a ram disk, configure and compile it 
the same way, all 96 tests pass.

OS is OpenBSD 3.6.

I'm currently running 7.3.5, which I'd love to upgrade but I'm a little 
leary until I can determine what is causing this error.

Any thoughts greatly appreciated!
