for instance, instead of:
(fhpd) attach my-program 1234
(fhpd) attach 1234
is suffcient as the program can be obtained from the running executable.
The HPD command set, has querks that I think can be traced back to trying to
support remote systems - "pid" might be remote, program local.
* hpd/CLI.java (attach): Don't require executable name.
(fhpd) attach 14901
runState state = 0
Attached to process 14901
I'm adding a test a part of the TestFhd cleanup.
