Patch 45 commentaried!

this patch was the mirror image of patch 44, called to actually send a process either home, or remote. theres some discrepancies between the two processor context send/recv functions i'll have to fix, an of course the vma file handling is broken, which is the thing that needs fixed to call this all 'beta' quality.

personally, recovering from patch 44 was hard. that was really like hitting myself in the head with a hammer. i've only got 5 more patches that should be near that ugly, however.

in theory, it should possible to migrate processes from ia32 to AMD64, and back. in practice.. the code isn't written for it.

while digging through this process teardown/buildup code, i can almost "smell" a process suspend-to-disk procedure, which would be neat to have on hand for things like kernel reboots without losing userspace state. likely also handy for suspend to disk, where you don't any longer have to 'save' userspace. outside the range of the problem i'm solving at the moment, however. process migration is such a big problem.. its truely overwhelming.

having watched the new Battlestar Galactica, i really feel some similarities between events in that, and how i ended up with this mess in my hands. unfortunately, none of my local friends are up-to-date on the series, so i can't talk about it. annoying!

its about time for classes to be over for the university students. i'm wondering how many of the irregulars will show up to the project this year.
