I met a problem
when I register PROCESS and PARK event use switch_event_bind_removable.
In my view,In normal sequence,PROCESS call back first and PARK callback second.
But sometims PARK is callback first and PROCESS callback second. And in different thread.

The out-of-order problem Bothers me.

my dialplan:
<action application="ring_ready" />
<action application="park" />

event time is same,but out of order and in different
last number is thread number
