If I try and run that command (with linux instead of osx and 64 instead of 32, 
since I'm on 64-bit Linux), I get a ton of linker errors, so I don't know how 
to compile and run the tests individually.

Running that binary is more or less instaneous for both debug and release, so 
running the tests has neglible running time. Compiling and running all of the 
unit tests and trying to time std.range with a stopwatch gives me about 15 
seconds for both debug and release (but it could easily vary by a second or 
two for both of them).

So, if you're saying that running the unit tests is taking 26 seconds in debug 
and 22 in release, I'm not seeing anything like that. On the other hand, if 
you're saying that the compilation takes that long, then I'm probably seeing 
something similar (since I can't get exact times and our hardware differs, I 
obviously can't be sure that I'm seeing the same thing, but it's close).
