For the record, i've not had any trouble with soft dep. on SPARC and
Alpha.  I generally stay a little behind the bleeding edge: i run releases,
not -current.

As far as i can recollect, i have had no trouble with soft dep. on either
 of those platforms with 1.6.1, 1.6, 1.5.4 or 1.5.3.

The "/local"s on each of these machines is a somehwat busy file system.
The contain my source trees (NFS mounted on various hosts) and the local
build areas.  I'd estimate that infrequently, they are fairly heavily for
hours.
