I made some changes to checkRemove() that implement what I
talked about
the other night. Unfortunately we seemed to have picked up a
lot of time
on the depcheck in my tests and it's all when we search the
tsInfo for
things that might require something we're
removing/obsolete/updating.

I'm a little blurry right now from sleep deprivation but I
can't think
of a good way to speed up that look up. 

I'm open to suggestions.

Not much help, however 3.1.5 is fast enough: to depsolve 160
updates in 
345M is 50 seconds, great!

With CVS HEAD  the story is different, the problem seems to
be that each 
check is slow,
I only get a line per second in output like this:

looking to see what requires 
('/usr/src/kernels/2.6.20-1.3023.fc7-i686/arch/arm/mach-pxa/
Kconfig', 
None, (None, None, None)) of dkms - 2.0.16-1.fc7.noarch
ooking to see what requires 
('/usr/src/kernels/2.6.20-1.3023.fc7-i686/arch/arm/mach-pxa/
Makefile', 
None, (None, None, None)) of dkms - 2.0.16-1.fc7.noarch

With 15000 files in kernel-devel it will take over 4 hours
to depsolve 
this package, (no I don't want to verify that).
