- ff0003 INSN3 <-- TP2, collect $regs
- ff0004 INSN4 <-- TP3, while-stepping 10 collect $regs
- ff0005 INSN5

- Notice that when instruction INSN5 is reached, the while-stepping
- actions of both TP1 and TP3 are still being collected, and that TP2
- had been collected meanwhile. The whole range of ff0001-ff0005
- should be single-stepped, due to at least TP1's while-stepping
- action covering the whole range.
-
- On the other hand, the same tracepoint with a while-stepping action
- may be hit by more than one thread simultaneously, hence we can't
- keep the current step count in the tracepoint itself.
-
- This is the head of the list of the states of `while-stepping'
- tracepoint actions this thread is now collecting; NULL if empty.
- Each item in the list holds the current step of the while-stepping
- action. */
