Comment 1 Phil Muldoon 2007-09-07 01:25:40 UTC

	* FocusCommand.java (handle): Build debug, stack-trace and frame
	info for newly focused set.
	
	* CoreCommand.java (handle): Add coreProc to idManager.

	* CoreComamnd. java (handle): Simplify. Let manageProc build
	set. Do not use StaticPTSet. Find main task, and generate
	stack-trace.
Comment 2 Phil Muldoon 2007-10-15 09:32:35 UTC 
This issue was a legacy issue with how fhpd used to handle processes, and how it
now handles them with sets. The CoreCommand.java has been rewritten to use the
idManager instead of building and maintaining sets manually.
