So I was about to give that a shot again. That this has been running
doing for 24hrs was bugging me. I ctrl-c'd the current run, and trinity
just sat there, because all of its child processes are stuck in D state.
The stacks show nearly all of them are stuck in sync_inodes_sb
iotop & vmstat shows there is _zero_ io actually happening.
So it's spent most the night doing next to nothing useful afaict.
Chris ?
Here's the /proc/pid/stack's of those children..
