TODO

-Some things which are to be done
---------------------------------
-
-- to restore anonymous shared pages safetly we need a global
-  mutex so there will be no activity on another thread until
-  mmap+page_read pair finish its job
-- cgroups should be used instead of explicit task stops by signals
-- dump/restore of network connections
-- dump/restore of IPC
-- (by Pekka Enberg) add a 'make check' or tools/test script that people can run to
-  do a full fork/dump/restore/kill cycle
-- cr-restore.c should be significantly refactored
-- 'crtools show' should support showing only a subset of resources dumped such as
-  pipes/vma/ and etc...
-- add bash completion file
-
-Some notes on code
-------------------
-
-- need to handle out cr_fdset(s), they are getting used more frequently
-  than I initially thought, including the usage only of a few file descriptors
-  while the whole set is always allocated
