Subject: [PATCH] somehow some people are getting situations where the payload
 doesnt decompress.  wtf? do i need to wrap the Input/Output streams we use to
 pipe data over the net with a verification wrapper for the messages? e.g.
 prefix the serialization of all I2NPMessages sent on the wire with the SHA256
 of that serialization and verify on read? Ho hum, dunno.  maybe its something
 else, but the ElG/AES+SessionTag already has integrity verification so the
 only thing I can think of is a checksum error that got past TCP's checking
 and corrupted the AES stream.
