Looks like there are 3 possible uses of the threads/smp USE flags: 1) Add support for a threading API in a library/language (for example in dev-lisp/sbcl) 2) Add support for threading in an application (www-servers/apache, for exmple) 3) Add support for a multi-processor machine -- this is different from (2) in that the application doesn't really gain anything if this is used on a uni-processor machine (sys-cluster/charm seems to fall in this category) I guess it would be consistent to use "threads" for (1) and (2), and "smp" for (3). Now, as for Gimp, grokking through the sources shows that "--with-mp" basically lets some processing stuff run in separate threads. This is clearly only useful on SMT/CMP/SMP machines, so I think USE=smp is fine. The user's complaint could be valid, though. Perhaps "smp" should be a global USE flag.
