Broken make release

[John Polstra]

Make release using sources from yesterday (June 16) seems to be
broken.  These two commands are failing:

    umount: unmount of /mnt failed: Device busy
    umount: unmount of /dev failed: Device busy

I'll include a bigger snippet of the output below.

My src/release/Makefile is standard except for these additions:

> BUILDNAME=    5.1-20030616-SNAP
> CHROOTDIR=    /a/release
> CVSROOT=      /home/ncvs
> MAKE_ISOS=    YES
> NODOC=                YES
> NOPORTS=      YES

I built a release on May 7 without any problems.

Here's a bigger piece of the log:
