// this test was isolated from nsAtomTable.i; a change was made in
// nsAtomTable.i to remove the failure here, but the fix was NOT that
// which I present here; the fix was to just comment out the line
// corresponding to the line at the bottom here where the ctor is
// actually called; this was done because attempting to fix it the way
// I have here somehow allowed another failure, where as the way I
// fixed it removed all failures
