/* Given `while-stepping', a thread may be collecting data for more

than one tracepoint simultaneously. E.g.:

|
ff0001 INSN1 <-- TP1, while-stepping 10 collect $regs
|
|
ff0002 INSN2
|
|
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. */
