Neil Conway commented on MESOS-4853:
------------------------------------
Another option might be to arrange (via a new libprocess API?) to temporarily
get a dedicated OS thread in which to use the synchronous API. Not sure which
would be cleaner/simpler.
> Considering using libcurl multi interface to implement 'curl' in Mesos.

> Currently, some URI fetchers rely on 'curl' command directly (using
> subprocess). This is not ideal. The libcurl easy interface is blocking, so it
> does not compose well with our async environment. However, the multi
> interface seems to be suitable for our async environment. The tricky part is
> that we need to hook the fd selecting logic with our underlying
> libev/libevent runtime, but this should be doable.
