Quick pcheck visibility scan of the full tree, stats follow:

mips profiles still enabled:
* 116191 seperate dependency issues, 1 line per profile/dependency 
  issue
* roughly 2m39s run time

mips profiles disabled (leaving mips-irix however)
* 9550 seperate dependency issues, 1 line per profile/dependency issue
* roughly 1m54s run time.

So... mips accounts for about 30% of the pcheck runtime, and *92%* of 
known visibility issues.  As for the runtime difference between 
pcheck/repoman, pcheck has some tricks internally to reduce the # of 
profiles it has to scan down to just the unique USE/mask set- I'd 
expect the mips impact to be far larger w/out that trick in place.

At the very least if it's going to be kept around, experimental or 
not, the number of profiles in use there *really* needs reduction- 
mips has roughly 117 profiles listed in profiles.desc out of 217- 
literally ~54%  of all dev/stable/experimental profiles.

Either way, stats to chew on.
