Comments

Generally, the kernel-mode stack cannot be paged; it is guaranteed to be resident in memory. However, Windows occasionally pages the kernel stacks of inactive threads. This flag prevents these occurrences.

The kernel debugger can provide information about a thread only when its stack is in physical memory. This flag is particularly important when debugging deadlocks and in other cases when every thread must be tracked.
