What RAM disk has this ridiculous limitation?

Did you take care of pointing TMPDIR environment variable to the RAM 
disk, when you measured this?  If not, the slow-down from writing 
temporary files to the hard disk completely overshadows the gains of 
having programs on the RAM disk.

You also need to set COMPILER_PATH and other environment variables, 
otherwise GCC will still invoke the compiler passes from the hard disk, 
not from the RAM drive.
