OBJ_KERNEL_HANDLE on NT4

As it is know OBJ_KERNEL_HANDLE flag is invalid on NT4.0 systems. The
question is if create a handle in nonarbitrary thread context (i.e. system
worker thread) will it be valid in every other thread context or in system
thread context only?

The handle will be valid only in system thread context. Every process has
separate handle table and handle is an index into the table.
Windows 2000 introduced separate handle table that is accessible only from
kernel mode. OBJ_KERNEL_HANDLE is used to create handle in this global
table.

No, in system threads only.
