Re-work some of the guts of the reconstruction code. Reconmap used to have one pointer for every reconstruction unit. This does not scale well in the land of 1TB disks, where some 100MB+ of "status pointers" are required for typical configurations. Convert the reconstruction code to use a "sliding status window" which will scale nicely regardless of the number of stripes/reconstruction units in the RAID set. Convert the main reconstruction loop to rebuild the array in chunks rather than in one big lump. As part of these changes, introduce a function to kick any waiters on the head separation callback list, and use that in the main reconstruction event queue to wake up the waiters if things have stalled. (I believe this may fix a race condition that could occur at at least at the very end of a disk during reconstruction under heavy IO load.) Thanks to Brian Buhrow for all his help, support, and patience in testing these changes.
