121
122 Currently, we only guarantee that I32 is *at least* 32 bits.
123 Specifically, if int is 64 bits, then so is I32. (This is the case
124 for the Cray.) This has the advantage of meshing nicely with
125 standard library calls (where we pass an I32 and the library is
126 expecting an int), but the disadvantage that an I32 is not 32 bits.

764 * the thing is that STDERR gets closed (as do all
765 * the file descriptors)
766 * - no deeper calling stack than the caller of the Newx()

768 * utility to you?
769 * - the function prototypes for the logging functions
770 * probably should maybe be somewhere else than handy.h
771 * - one could consider inlining (macrofying) the logging
772 * for speed, but I am too lazy
773 * - one could imagine recording the allocations in a hash,
774 * (keyed by the allocation address?), and maintain that
775 * through reallocs and frees, but how to do that without
776 * any News() happening...?
