Don't try to erase secrets from memory.
...
1. The things we're really trying to protect - contact identities,
message contents, etc - can't be erased from memory because they're
encapsulated inside objects we don't control.
2. Long-term secrets can't be protected by erasing them from memory
because they're stored in the database and the database key has to be
held in memory whenever the app's running.
3. If the runtime uses a compacting garbage collector then we have no
way to ensure an object is erased from memory.
4. Trying to erase secrets from memory makes the code more complex.
Conclusion: Let's not try to protect secrets from an attacker who can
read arbitrary memory locations.

Application layer keepalives to detect dead TCP connections.
...
DuplexOutgoingSession flushes its output stream if it's idle for a
transport-defined interval, causing an empty frame to be sent. The TCP
and Tor plugins use a socket timeout equal to twice the idle interval to
detect dead connections.
See bugs #27 , #46 and #60 .

Interrupt all messaging sessions when the app starts shutting down.
...
This makes it more likely that connections will be closed cleanly.
However, the interrupt() method is currently ineffective for incoming
sessions as it won't interrupt a blocking read, e.g. when the packet
reader is waiting for a packet.
