3rdparty/libprocess/src/libevent_ssl_socket.cpp (lines 808 - 810)
<https://reviews.apache.org/r/49280/#comment204985>

    I would have expected this note to appear above `evconnlistener_new`.
    
    Here I would expect a note explaining that a library implementation should 
not be opinionated about `cloexec`, and rather delegate that decision to the 
user.
    Take the linux socket as an example:
    http://man7.org/linux/man-pages/man2/socket.2.html
    
    We should either:
    1) parameterize the socket interface to expose this option, and maybe 
provide the default that is most commonly used by libprocess. On the flip side 
you should argue that the default should be the one of least surprise, which 
would be *not* to provide `cloexec` in line with the linux API.
    2) add a `TODO` here that explains this predicament, and point to the JIRA 
to take on this cleanup work.
    
    I propose #2 as we're trying to fix a bug before a release, and may not 
spend sufficient time to think through #1 correctly.
    This also seems like something that would be a valuable contribution by a 
community member.
    
    The same would apply for the `connect` code at line 489

    Is this behavior consistent with the other implementations?
    If an error occurs, we don't propagate it to the `acceptor`?
    I think a comment is necessary here to explain what behavior we're 
accomplishing.

    Since we're trying to consistently use `cloexec` in this implementation in 
the interim, why do we not need to use `LEV_OPT_CLOSE_ON_EXEC` here?
