Well, das@ is still listed as my mentor, so I need approval
from him to commit. He did indicate to me that if you approved
a patch, I could commit it. Our usual exchange follows:
here:
1) I send a (possibly new) diff.
2) you tell me that you've made some refinements to the algorithm(s)
or there are style(9) issues.
3) I integrate your changes (where upon I fat finger something to
introduce a new style(9) issue).
4) I then spend a week or so testing the changes on i386, amd64, and
sparc64.
5) Generate a new diff and send it to bde.
6) Get busy with life.
7) goto here.
