In case anyone was interested. The madmen at UNSW are porting Darwin
(the mac os x unix portion that used to be freely available until the
intel macs came out) to L4
http://www.ertos.nicta.com.au/software/darbat/
I know Qualcomm also uses L4 in real production hardware now for
embedded systems.
You can't lump all microkernels together. Mach was/is a really poor
microkernel compared to others of today's standards. QNX has a much
better one as well.
