Hmm, I've tested this on fresh -CURRENT and -STABLE UP boxes,
and on SMP bento, and I cannot reproduce this behavior with
new make(1).

It also seems to depend heavily on the location of "src/"
and of the value of MAKEOBJDIRPREFIX.  I get best results
with MAKEOBJDIRPREFIX pointing to NFS homedir, but the
result in this case is unstable:

			old make	new make

/usr/src +		4,99s		29,85s

/var/tmp/ru/src +	5,05s		29,80s

/usr/src +		5,48s		14,45s 6,65s

/var/tmp/ru/src +	5,34s		12,84s 2,74s

In any case, this seems to be an issue specific to
this machine, so nevermind this post.
