Details

Over 3mb of memory is burned on IL in TT.  The uncompressed swf is only 600k or so, usually we get 2 IL instruction per abc opcode, but that translates to 4x space usage since IL opcodes are 16 bytes.  Thoughts:

1) we need a tighter IL
2a) we need a IL cache, ie the ability to evict infrequently used IL or
2b) if we can make IL denser we could potentially keep it all and look into ditching the abc
The 3mb # comes from the Flex checkinapp
s/IL opcodes are 16 bytes/IL opcodes are 16 bits/

but yeah, point is taken :-/
TT's on ice
