OK, here it goes:

I'm developping a kernel module that needs to delay a process, that is, he
receives a PID and, when a specific event occurs, that process shall be
delayed. This delay shall be done in a way that the process keeps burning CPU
time (it can not be, e.g., put in a waiting-list...).
The solution I found was to change its code segment, putting a loop in it.
After a specified period of time, the original code must be restored and the
process must keep going as nothing happened.
The main problem I found was already explained: can't write to the CS!
