> (does kernelland have anything like the "watch-point" feature in
userland debugger, to detect when a write -- or as the case may be here, a
read! -- occurs into a memory area?)
In KDL you have the commands `watchpoint` (set/clear) and `watchpoints`
(list). You can set the watchpoints programmatically via the kernel
private API `arch_set_kernel_watchpoint()` ([http://cgit.haiku-
os.org/haiku/tree/headers/private/kernel/arch/user_debugger.h?id=694be58ab1d6828b9d735403abb5d5354ffc009d#n42
declared in <arch/user_debugger.h>]).
