Just for fun I tried compiling some kernels with "ccache".

It cuts the time it takes to compile LINT in half.

And that is on a dual-athlon-1800 system with 2GB RAM and 15kRPM
scsi disks, slower systems will see larger improvements.

There about 100 files overlab between kernels, probably mostly stuff
in libkern.

Conclusion: Most people can probably benefit from using ccache.

It's actually a pretty neat idea, which (despite what O'brien
will yell at me) I would suggest should be put in the compiler

Never attribute to malice what can adequately be explained by incompetence.
