Weird script stack entries at block #227837? At block 227837 , the coinbase TX 


  e35ca7413b61397a49551fea6ebb540988afcf4a2d0e750773d38eb11b138f40


has the following script:


  03fd790304000037e4124d696e656420627920425443204775696c6408000000fb00001e0b


Which translates to:

03 = push the next 3 bytes to the stack ==&gt; ok
fd7903 , the 3 bytes which are the block height ==&gt; ok
04 = push the next 4 bytes to the stack ==&gt; ok
000037e4 , the 4 bytes which are pushed to the stack ==&gt; what's that?
12 == push the next 18 bytes to the stack ==&gt; ok
4d696e656420627920425443204775696c64 = "Mined by BTC Guild" ==&gt; ok
08 == push the next 8 bytes to the stack ==&gt; ok
000000fb00001e0b ==&gt; what's that?


So, what is the meaning of "000037e4" and "000000fb00001e0b"? Are they just some pool related nonce bytes, or is there a deeper meaning related to the signature?
Coinbase inputs have no requirements to be valid scripts, or any particular data at all other than the block height defined in BIP34.
