[Bug general/3761] New: fstep is really, really slow

["mark at klomp dot org" <sourceware-bugzilla@sourceware.org>]

fstep is partially so slow because it accesses the Task memory for every
disassambly. Maybe that can be cached? Although instruction stepping is
just slow in general. An alternative could be combining stepping with
breakpoints set on "interesting functions". Or only stepping while in
the main program map, and not in any of the shared library maps?

Memory access is not only slow for fstep. Other programs (like fcore) also could
use faster access to the inferior memory.  One idea (at least for read access)
is mmapping the inferior address space (/proc/<pid>/mem), and/or performing
larger transfers and caching under the hood.
