The general idea makes sense to me, but I'm not sure we really do need
a klist here, since the usage profile of this list is expected to be
super simple: very small number of accessors, looking for small number
of list members a small number of times, and probably never do need to
modify the list while accessing it.

I suspect that the code would be simpler to maintain, debug and
understand if we just use a simple list with a simple locking
methodology here.

Thanks,
Ohad.
