That could make sense. No matter if you pool handles or not, curl is always
best used when not doing cleanup/init but instead just re-using the same
handle over and over again.

There might be reasons why you need to consider how you go ahead and
Each "easy-handle" keeps the last N connections open and alive if possible
for persistant connection reasons. Thus, you probably want to re-use the very
same handle again when re-issuing a request to a host a second time...
Doing this with many requests for each handle may also result in quite a
large number of connections kept alive, which isn't a problem as long as
you're aware of it.

Not that I know of.
