Add more agressive memory allocation calls
If we hit a situation where we can't allocate a page of memory,
this will force a coalesce (defrag) a few times and then
eventually trigger other memory reclamation actions.
Also tweaked a few spots in the kernel to enhance debug:
- add more stops to look at errors (HB_BREAK_ON_ERROR)
- add more backtrace calls
- add a new debug flag to count the extra coalesce calls
