I am?  Well, if I need to give my opinion on this, then blindly
increasing the limit ten-fold is something that'd make me worry about
a potential C stack overflow.  I'd feel much better with a lower
factor, e.g. some value that is just enough to cover this case plus
some slack.  Bonus points for providing a defcustom with the factor,
so that users could change that.

The idea of asking the user whether to increase by N levels sounds OK
to me, provided that its implementation is not out-worldly hard.

Thanks.
