SUMMARY
=======
The following information describes how the LRU (Least Recently Used) list is
updated in Windows.
When a function in a code segment is called through its thunk, one instruction in
the thunk is to update a record in the EXE header. This is done to notify
Windows that a segment has been recently accessed. Windows updates the LRU list
periodically according to the records. The routine that does the job searches
for segments that have been accessed since the last time the routine was called.
When it has been determined that the list needs to be updated, the routine
resets its reference byte and puts it at the top of the LRU list. By default,
the updating routine is called every four timer ticks from the INT 8 handler.
