src/slave/containerizer/mesos/isolators/cgroups/subsystem.cpp (lines 674 - 677)
<https://reviews.apache.org/r/45363/#comment202323>

    I see here we call `lambda::bind()`, but in the original `cgroups/mem` 
isolator, we call defer():
    
https://github.com/apache/mesos/blob/0.28.2/src/slave/containerizer/mesos/isolators/cgroups/mem.cpp#L605:L609
    
    That means `MemorySubsystem::oomWaited()` will be executed in a separate 
thread. So my concern is there may be some multi-thread race condition issue 
for your way, e.g., what if `MemorySubsystem::oomWaited()` is triggered after 
the container exits (i.e, we have cleaned it up)? I think in the original 
`cgroups/mem` isolator, we have already considered this issue, please refer to 
this comment for details:
