[PATCH 0/4] _pager_do_write_request fixes

[Sergey Bugaev]

This is the same patch, split into three for readabilty and
reviewability. I'm still looking for feedback :)

Instead of removing the munmap from _pager_do_write_request (),
document that pager_write_page () is *not* supposed to unmap the
page (nor keep references to it), and remove the munmap call from
storeio.

Sergey Bugaev (4):
  libpager: pager_write_page () should not unmap page
  libpager: Store omit_data in an array
  libpager: Track which pages are precious
  libpager: Do not throw away precious pages
