The code we are writing is a debugger for operating systems written by
students in our school. This debugger should not use the PIT because we
want it to be freely available for the students, without using any given
library ! If it is impossible, we will have to try to reprogram the timer
and the IDT each time we switch between the context of the debugger and
the context of the debugged program... It could work, but it is not really
clean.
