 NOTE(shess): On Ubuntu it is possible to run the tests in a tmpfs something
 like:
 
 TMPFS=/dev/shm/sqlite_build
 BUILD=$PWD
 mkdir $TMPFS
 (cd $TMPFS ; $BUILD/testfixture $BUILD/../test/veryquick.test >/tmp/test.log)
 
 This is faster, but it is plausible that different things are being tested than
 real-world use.
