Re: [libmicrohttpd] Needed enhanchments

[Christian Grothoff]

Hi!

Yes, we would be open to incorporating epoll/poll or similar more scalable 
system calls into MHD.  The only major requirement (other than clean working 
code) is that it should be made portable using configure/autotools: the code 
should be automatically disabled for platforms that don't support it 
(reverting to select) and on platforms that do support it there should be an 
option to explicitly disable it (primarily so that we can also continue to 
test the select code...).

Feel free to open a feature request for this on Mantis indicating that you're 
working on it (if you are), so that we don't have someone else do the same...

Best,

Christian
