Thank you!  Very cool to see the example working.  Funny, I
implemented MHD_get_timeout in the main loop in my project but in all
my tests it always returned MHD_NO, so I assumed it was not applicable
to my use case and didn't include it in the example I wrote.  But I
didn't make the connection that it *also* had to be called after
MHD_resume_connection until your response here.  Would you consider
the attached patch?   It adds one line to the docs that I'm quite sure
would have pointed me in the right direction had it been there before.

Thanks!
Bob

fix 'race' between MHD_epoll and MHD_daemon_quiesce on epoll listen FD removal, resolve simply by allowing syscall to fail with ENOENT

remove dead IN_CLEANUP state, revert previous patch that called completed callback from wrong thread
