Comment:

 The problem is that when compiling `A.hs-boot`, module A's hs-boot file is
 added to the finder cache instead of its corresponding source file. So
 when the interface file for module A is requested, the finder cache
 returns "A.hi-boot". It then appends "-boot" to the end of that to get "A
 .hi-boot-boot".

 Since it is assumed that every home module location in the finder cache
 corresponds to a source file, the correct solution is to always add the
 module's source-file location to the finder cache, even if the current
 file happens to be an hs-boot file.
