I'm looking for a solution for 4.6+ as well as we want to avoid to have
to maintain too much patches for a long time.
So right now I'm trying the pthreadpool_tevent way. I haven't looked
very deeply at the implementation, only at your torture tests and the
use in vfs_default.c
If the structure is shared across threads is the API taking care of
locking/unlocking access to the memory ?
Quick glance seems to indicate that it's not but I wanted to confirm
this, or maybe you highly recommend to use non shared memory to avoid
