NetBSD's non-disconnectable SCSI implementation could be a factor in this.
It means that when doing tape I/O from another terminal, you can't interleave
any other SCSI I/O operation while waiting for a pending SCSI tape command
to complete.  Or any SCSI command, but tapes take long enough to be really
noticeable.  The connection would be that swapping requires SCSI I/O, and
the problem seems to relate to I/O and low memory.  Just pure BS speculation,
but I thought folks might be interested to recall this aspect of NetBSD's
SCSI support, as it is different from what they might be used to.
