I _think_ that the abstract points out that reference-counted garbage
collection can be done deterministically. Haskell could some day be an
excellent replacement for C/Ada in safety critical markets, but some serious
changes to the RTS (most having to do with memory allocation, garbage
collection, and multi-threading) would have to be made.

If the GC becomes deterministic, then a much better case can be made for
using the language on a plane or in medical devices.
