We need a heuristic and global facility for detecting low memory situations and triggering drain functions around the various caches and free lists that exist in the kernel (page cache, object caches, etc). This is open to interpretation / design.

Memory management: add generic memory cleaner interface
339ce1d 
With this change, it is possible to register different "memory
cleaner" closures, which will be invoked to free up memory when the
system is low on available physical memory. The virtio balloon
deflater and the pagecache drain function have been converted to
use this interface.

Partially addresses #1130.
