Open a random process without debuginfo in the source window.

Then click "continue" to attempt to continue execution of the process.

A core error dialog comes up with:

Looks like this is caused by a combination of:

t.requestDeleteInstructionObserver(this);
t.requestUnblock(this);

in RunState.run(LinkedList).

Blocking by #4051

My little test program:

int main (int argc, char **argv)
{
  int i = 0;

  while (1)
    {
      if (i > 0)
        i--;
      else
        i++;
    }
  return 0;
}

I use fhpd to attach to this running program:
attach test1 0000
break test1.c 10
go

Without the call to requestUnblock the process won't continue.

Temporarily worked around:

Log message:
	frysk-core/frysk/rt:
	2007-02-16  Mike Cvet  <mcvet@redhat.com>
	
	* RunState.java (swContinue): Added. Temporary workaround for
	#4057.
	
	frysk-gui/frysk/gui/srcwin:
	2007-02-16  Mike Cvet  <mcvet@redhat.com>
	
	* SourceWindow.java (doContinue): Temporarily calls
	RunState.swContinue() as a workaround for #4057.
