  That will still slow down the common case.  The way I see it, we have to 
create a function pointer that points to implementions of different PSD 
approaches and choose the right one accordingly.  Slowing down PSDs is the 
last thing we want based on the recent profiles.  The tradeoff is that we 
have code duplication.  Maybe we can work around this with the preprocessor 
and/or the build system somehow.
