 If one wants to build a virtual raster with GdalTools, there is a limit of
 32767 characters for all of the input file path names combined. A quick
 Google search revealed that 32767 is the range of an integer, so it seems
 that that's where the problem lies.

 In my test case each file path was 61 characters long, so that limits me
 to 537 tiles per virtual raster. Even if I moved all of the rasters to the
 directory root and renamed each tile with a shorter name, I could only get
 the path for each file down to 15 characters or if I wanted a tile naming
 scheme that still makes sense. That said, even then I'd be limited to 2184
 tiles per virtual raster.
