Summary:                    One-touch parking results in stuck/deadlocked
channel if parked channel hangs up while announcement still being played
Description: 
This is a continuation of issue 11979. I discovered it just after I
reported everything's fine and that issue got closed. I don't see a way to
re-open it, probably because I'm not the original reporter, so I'm opening
a new issue.
The setup is exactly as I described in 11979:
- features.conf:
[featuremap]
parkcall => *30                ; Park call (one step parking)

[applicationmap]
park_caller => *33,peer/callee,AGI,park.agi|park_caller
park_callee => *33,peer/caller,AGI,park.agi|park_callee

The scenario:
2 SIP endpoints: xyz011101(polycom 501) calls xyz110001(cisco 7960), call
is connected (through FastAGI application), then I dial *30 on xyz011101 to
park the peer and hangup the peer (xyz110001) while announcement being
played to xyz011101. The result is xyz011101 is stucked. It appears in
channel list after I hang it up on the phone and sometimes (intermittently)
asterisk crashes or deadlocks after that.
Here's the console output:
    -- Executing [1100 at xyz:1] Set("SIP/xyz011101-081e15f8",
"TIMEOUT(absolute)=10800") in new stack
    -- Channel will hangup at 2008-09-04 23:48:14 UTC.
    -- Executing [1100 at xyz:2] AGI("SIP/xyz011101-081e15f8",

  == CDR on channel 'SIP/xyz110001-081e2b88' lacks end
  == CDR on channel 'SIP/xyz110001-081e2b88' lacks end

Whoa, failed to remove the extension!

    -- Added extension 'isk/var/lib/asterisk/sounds/digits/en/1.al'

At this point I hangup xyz011101 and do "show channels":
webdevel*CLI> show channels
Channel              Location             State   Application(Data)

1 active channel
1 active call
A few minutes later asterisk crashed
