Still, Miklos noticed some problems with it.
I'm not talking about doing things on top of the current signal-based
freezing mechanism, but rather about moving the freezer a bit closer towards
the scheduler. Maybe this is the way to go. I don't know.
In any case, the freezing of user space seems to be much simpler than modifying
all drivers to add suspend synchronization.
Thanks,
Rafael
