Mach4/GNU Mach Features
I was reading some of the notes on the Mach 4 website linked
from the GNU Mach web page.
Does GNU Mach contain the "new features" (circa 1997) listed
on this page as already being incorporated into Mach? For
example, the most-recent HP-PA version of Mach 4 supported:
- Migrating threads
- Kernel Activations
- Presentation/Interface IPC
All of these were shown in the literature to have positive
impacts on memory use and overall performance.
