Re: [libmicrohttpd] Lots of CPU usage with MHD_USE_POLL

[Christian Grothoff]

Hi Boyan,

I don't know what version of MHD you are talking about, but in both SVN HEAD 
and MHD 0.4.5 (the only released version with support for poll), the third 
argument given to 'poll' is already "1000".

Best,

Christian
