This does not happen on my machine - the program just never returns
It doesn't seem to use CPU time it just *hangs* (seem's like I'm not the only
one too) - I verified that I'm using R9B-1 (latest and best TM)

This I don't understand. My /usr/include/values.h doesn't
define MAXDOUBLE I found this (eventually)
#define GSL_DBL_MIN 2.2250738585072014e-308
#define GSL_DBL_MAX 1.7976931348623157e+308
This is what I also found in a document describig the format of
IEEE 754 reals. (I'm assuming that Erlang floats are actually IEEE 754
64 bit reals) is this so???
