Out-weaseling Firefox

There has been a lot of buzz lately about the Firefox 3 fsync issue. The work I’m doing these days has me doing a lot of long-running disk-bound activies, so this one hurts me pretty bad. Firefox would stop responding for 30-40s at a time while my job was running in the background, which I think is pretty unacceptable. I have worked around it in the (hopefully) short-term with a LD_PRELOAD hack. I’ve posted it here in case anyone else finds it useful. Just unpack, cd to the directory, and ‘make && make install’ (not as root). A word of warning, though: if it breaks you get to keep both pieces. Kudos to Aaron for adding the ‘make install’ bits to the Makefile
