[distcc] distcc speedup

[Michael Santy]

All,

In looking at the sources to distcc in adding support for MSVC, it 
appears that the preprocessed source is being written to disk on the 
client, and read from the disk and sent to a server.  Wouldn't it be 
faster to tell the compiler to output the preprocessed source to stdout, 
and redirect that directly to the server?  Maybe I'm missing something.....

Thanks,
Mike Santy
