Let's look at situation like building mozilla with pkgsrc when everything
(/usr/pkgsrc, /usr/pkgsrc/distfiles, WRKOBJDIR) is mounted via NFS:

	- checksum:
	  - fetch whole mozilla source tarball via NFS
	  - calculate checksum
	  
	- extract:
	  - fetch whole mozilla source tarball (again) via NFS
	  - extract every piece of data back via NFS (size of tarball
	    multipled by at least one point something)

This can take some amounts of time. While doing one package, time doesn't
matters as much, as when bulk building.

Do you have any ideas how could I get around this?

I thought about extracting packages on the NFS server first. Why not, this
could possibly work (except I won't need package dependencies to be
installed on NFS server, which is normal behaviour of "make extract") . The
next problem is, anyway, that if I want to build single pkgsrc tree on some
more hosts, than one, all of them will create "work" directory in pkgsrc
tree, which will cause other builds to be confused by other (even with
WRKOBJDIR symlinks are created). What solution -- except mount_union or
obvious, cp -R pkgsrc pkgsrc2 do we have for such problem?
