Description:
------------
The instructions contained in KnownIssues.txt do not solve the problem:

	Persistent handles and "cookiestore" request option do interfere,
as libcurl saves the cookies to the file on curl_easy_destroy(),
cookies are not saved until the CURL handle will be recycled.
Thus one would either need to
* run PHP with raphf.persistent_handles.limit = 0
* call raphf\persistent_handles_clean() every request
* call $client->flushCookies(), which is available
since libcurl v7.17.1 and does not work with the
procedural API

Calling raphf\clean_persistent_handles() and setting raphf.persistent_handles.limit to zero does not fix the race condition with cookiestore. Essentially the cookie store facility does not work properly.

The following steps reproduce the problem:

1) Send a POST request with login credentials that cause a number of redirects with Set-Cookie headers.
2) Then create a new request and send it - the cookies will not be sent.
3) If the same cookie store file is preserved, the cookie store file (cookie jar) will be read after the next cycle.
