CLR thread vs kernel/native thread data structures in memory

In the current CLR, each "CLR thread" maps to exactly one kernel/native thread after it start running. Before starting, it maps to
no kernel thread.

There's a kernel data structure for each running thread, including the stack. The dotnet CLR thread enriches that data structure
with additional info. One important additional info is the GC info. For each thread, CLR needs to know how to find local pointers to
heap objects. Unencumbered with this special GC requirement, the kernel doesn't have this additional data structure. See P86
[[concur programming on windows]]
