some more points i've discovered:


	- if i attach to an already running process, i can set breakpoints
	quite happily and they work.

	- on the sparc, the calls to write target memory come _after_ the
	call to "run".  eg, if you do "break main", some things are setup,
	but the target memory isn't actually modified until "run".  on
	the alpha, there are no target memory interactions after "run"..


the latter makes sense -- you can't write target memory until the process
is actually running.  to it seems that this functionality is missing for
the alpha...
