Fix PDK Mounts
PDK apps currently leave mount points open after they exit. This can lead to having many more open and mounted filesystems than expected: <source lang="text"> tmpfs 65536 3064 62472 5% /var/palm/jail/com.ea.app.scrabble/tmp /dev/mapper/store-root

A solution is to run a shell script that will search for these mount points and remove them: <source lang="bash">
- !/bin/sh
for i in $(mount | grep 'jail' | sed 's/.*\(\/var\/palm\/jail\/[^[:blank:]]*\).*/\1/'); do umount ${i} 2>/dev/null; done for i in $(mount | grep 'jail' | sed 's/.*\(\/var\/palm\/jail\/[^[:blank:]]*\).*/\1/'); do umount ${i} 2>/dev/null; done </source>
The operation is intentionally performed twice because the /var/run/dbus mounts must be unmounted after all the other ones.
