I could be wrong about this, but from what I remember this comes 
down to DMC's runtime library. The max number of open file 
descriptors with apis such as fopen is pretty low (about 70 from 
what I remember) when using DMC's C runtime (which DMD does use). 
I don't think you can do much about it besides making sure you're 
actually closing files when appropriate as some tests might be 
leaking open file handles.
