I hit the original bug on Solaris, so also tried this patch and similarly got
looping.   Stopping in the debugger it had gotten wedged in the loop in
ProcessWorkQueue because doListFontsWithInfo keeps sticking itself back in
the queue.   Getting rid of all the ClientSignal() calls added in this patch
stopped that.   (Still can't run xterm with a font path of just built-ins +
xfs, but that seems more deeply broken.)
