This is just a wild guess since I haven't looked at your code but I suspect sessions may be playing a role here, the following is from the PHP Manual entry on session_write_close():

Session data is usually stored after your script terminated without the need to call session_write_close(), but as session data is locked to prevent concurrent writes only one script may operate on a session at any time. When using framesets together with sessions you will experience the frames loading one by one due to this locking. You can reduce the time needed to load all the frames by ending the session as soon as all changes to session variables are done.

Like I said, I don't know what your code is doing but those graphs seem oddly suspicious. I had a similar issue when I coded a multipart file serving function and I had the same problem. When serving a large file I couldn't get the multipart functionality to work nor could I open another page until the download was completed. Calling session_write_close() fixed both my problems.
