This may cause difficulty in programming the application to deal with synchronization between callback calls and key registration (for example see ticket #460 and #469). This ticket adds an option in the ioqueue to disable parallel/simultaneous callback on the same key. Please see [http://www.pjsip.org/pjlib/docs/html/group__PJ__IOQUEUE.htm#pj_ioqueue_concurrency_sec IOQueue Concurrency Rules] in PJLIB documentation for more information.
