It seems that this change causes much more problems. My system kept crashing
or freezing frequently because of that change. Several attempts to complete
a NetBSD build failed because the system died. And my system doesn't use
any removable network interfaces (unless the unused "fw0" counts as a
removable interface).

After backing out the above change in my source tree the system stayed
up the whole night and completed a NetBSD build without problems.
Markus W Kilbinger reported similar problems. If backing out the
change fixes his problem, too, I will revert the last two revisions
in the NetBSD source tree.

        Kind regards
