Great news! Plus an easier way. BUT...

I see the point for killing the IE cache, but, it might well not be faster than doing it other ways. The point is, that all file i/o in unix is buffered via memory. This is done in such a way that with a good quantity of ram, the disk is very rarely written to. The vm system takes care of paging the 'dirty' file buffers to disk. I very much doubt if in osx the ram disk gets guaranteed ram residency. Therefore, when the system has need for extra pages, it too will be paged out to disk (and will sit there until paged in again). I may be wrong, but I think the only non-pagable part of the memory will be a set of core kernel code.

Cool hint though. I've been asked that a couple of times and couldn't work it out.
