I don't like very much the "Its use is discouraged." without any
information since in practice
1. it seems to be very well supported,
2. it can improve the efficiency (for instance, it was completely
removed from the MPFR trunk for a few days to fix a bug, as it
was also used for very large memory allocations, but I had to
re-add it for small allocations since the loss in small precisions
was important in raw timings, and could still be significant in
some practical applications).
Perhaps something like:
This function can improve efficiency in some applications compared
to malloc()/free(). Otherwise its use is discouraged.
