  When your \hfuzz is not large enough for the current box, you will

texmf.cnf instead.

  It's much easier to reproduce:  \hbox to 2pt{abc}.

  ConTeXt doesn't check your work, it happily lets you shoot your feet.
(IIRC, Hans “promised” to add argument checking whn his laptop hits the
10 GHz barrier.  I'm not sure if he referred to a Windows or Mac
machine, though, where the GHz numbers mean extremely different things ...)
