"Now" as in -current as against 8.x. But, that 2=BD mins was wrong,
sorry. I recalled "150s" but actually checking, it's really 1:50
(100s). It occurred to me that was an oldish -current (r235127) so I
updated to r236183 and the time dropped to 107s. Since this is an
oldish P4, I tried a UP kernel and that reduced it to 96s. Your patch
made no noticable change (ministat reported no difference with 95%
confidence).
The system is amd64 with no MK_* knobs defined.

I've done some investigating and the problem is that "xargs -n1"
fork()/exec()s /bin/echo on each file (and there are 5538 files for
me). Changing this to "tr ' ' '\n'" reduces "make delete-old" runtime
to 1.75s - which is much nicer. I've checked a variety of other
systems running 8.x & 9.x and the 97s seems to be anomalously long so
I'll do some more investigating.
