Sure, that makes sense.  The stat() call can't know, but the exec() 
certainly does know that it's trying to execute.  So I meant that exec() 
could call stat(), and if the file exists but is a directory, reject it 
as a possible thing to execute, and continue with what I assume is the 
existing Windows-specific logic to look for foo.exe or foo.lnk.

What do you think, does the idea make sense?
