As a developer, the philosophical side is #1 in importance.

A resource manager isn't a little patch.  It's a large, complex project 
which will take perhaps 6 months to code and test.  No one wants to 
spend those months and then have the code rejected for philosophical 
reasons.

If the community agrees that a RM in the kernel will be accepted if the 
code is of good quality and well tested, we can do it.

If the community won't accept the code under any conditions, tell us 
now.  We'll fall back on the user space resource manager, the limited 
resource manager in the kernel, and all the hacks required to have them 
work together.
