60daa414db Allow to checkpoint and restore a container with console 
runc already supports this case, so we just need to run it with proper
options.

9754696ff5 linux/prox: timeout fifo creation 
Under certain conditions in the client, the fifo for a container may not
be created. A timeout has been added to this operation to ensure the
shim can recover when the client fails to open the fifos.

cd72819b53 archive, cio, cmd, linux: use buffer pools 
To avoid buffer bloat in long running processes, we try to use buffer
pools where possible. This is meant to address shim memory usage issues,
but may not be the root cause.

74b3cb3391 Fix exit event handling in shim 
Could issues where when exec processes fail the wait block is not
released.

Second, you could not dump stacks if the reaper loop locks up.

Third, the publisher was not waiting on the correct pid.
