FYI:

Jon and I have now started the merge; I committed basic kernel capability mode 
support yesterday (cap_enter(2), cap_getmode(2), new errno values, 
capabilities.conf).  Over the next few weeks we'll merge man pages, additional 
kernel support for capability mode and capabilities, including delegated file 
system subtrees in capability mode, cap_new(2) and friends, process 
descriptors, and so on.  Kernel support for these features will remain 
conditional on compiling in options CAPABILITIES (and later options PROCDESC) 
for the time being.
