Re: RE: [rtl] malloc, timers, and crashes.

Two points:
	1) It's quite trivial to do kernel calls from RTLinux: look that
	the implementation of rtl_printf for an example. I posted two
	mallocs a while back.

	2) It's _wrong_ to call malloc from RT code.
		Malloc can suspend or fail (more realistically, any way of calling it
		from  RTL can suspend)
		If you can tolerate a suspend in RT code, you don't have
		a RT constraint.
		If you don't have an RT constraint - don't run in RT
		space. Allocate memory in a Linux driver and pass it to
		RTL
