What's the argument about just dumping the task's memory as is, with all 
breakpoints there? A corefile is a representation of that process and 
it's thread as it is at that time ...

And besides, this is only addressing a tiny corner case of someone 
running fcore on a process that is being debugged with Frysk at that 
time. I can't think of a scenario why I would do that. Can you? If they 
were debugging with GDB and fcore was run on that process, the included 
core image would have all the break point information.

It seems like a lot of work for a very small edge case?
