From the RE telecon this morning.

Add required features to 5.2-RELEASE list:

• Production-quality M:N threading (julian, davidxu, deischen)
• 16-bit CDB support in CAM (ken)
• FAST_IPSEC and KAME compatibility (unowned)
• KAME Synchronization (unowned)
• truss support for ptrace (unowned)
• Merge of Darwin msdosfs, other fixes (unowned)

Add desired features to 5.2-RELEASE list:

• MAC support for NFS Server (rwatson)

Note: in many cases, deciding to get these things working for 5.1 would
not be amiss either.
