It is because Linux uses _second_ as the unit of the TCP_KEEPINTVL and
TCP_KEEPIDLE.  In DragonFly, the unit of TCP_KEEPINIT, TCP_KEEPINTVL
and TCP_KEEPIDLE is millisecond, which is consistent w/ the related
sysctl nodes' unit.  I am not going to follow Linux on this; different
systems have their own unit of TCP_KEEP*, e.g. OpenVMS uses 0.5
second.  curl should be patched to fix their assumption about
TCP_KEEP* argument unit.

curl has been broken since version 7.25 on DragonFly. I've bisected it down (using https://gist.github.com/3013871) to this commit:

https://github.com/bagder/curl/commit/2a266c1c7c075f9faced0248ed3f870dac1fc749

I can't find any functional difference between the code removed there and the one added on the library side in that commit's parent, so I am at loss for producing a more minimal testcase.

Current curl works fine on both OS X and Linux and I can't see any OS-specific code there so I guess this is a DragonFly problem(?).

A workaround for using curl on DragonFly is invoking it as _curl --no-keepalive_.
