The timing should be roughly the same, but fluctuations in the low
percentage range are normal.

Interesting.  I could reproduce this and it was very certainly a bug
in the code, fixed in -25 snapshot and 1.7.35-0.4.

Sounds good to me.

Doesn't sound good at all.  Terrible in fact.  That a 32 or 64 bit XP?
I didn't fire up my XP test machines for ages and I'm not overly enjoying
it, but I guess I have to.  Oh well, hang on...

[...time passes...]

[...XP...]
[...32 bit...]
[...updating...]

Hmm, no.  In my case there's no visible delay starting mintty, and tcsh
is my login shell, too.  mkpasswd and mkgroup are running comparably
fast as on my W8.1 64 bit machine I'm using for testing in the first
place.

Something strange is going on on your XP machine, it seems.
