Hi Kevin, 

This is the last one, I promise.  I thought some of the identifiers in
aix-thread
were a little un-informative and/or inconsistant with other target
modules, so
I offer you this renaming.

And I humbly beg your pardon, but I was unable to resist sneaking a few
whitespace clean-ups in there too.  If you like, I'll re-submit them 
separately.

Michael
