[pmwiki-users] Multiple simulaneous downloads blocking, using PmWiki per page uploads, and auth

[Petko Yotov]

Thanks, this is reasonable, will add it (before the 404 block) for the 
next version.

The ramifications are that the session file is unlocked/freed after 
authentication but before the streaming, so a parallel download will not 
have to wait for the current download to end.
