 238  * in C on many archs such that it does not require a stack. However this
 239  * does not seem hugely important as only 64 byte are wasted. The 64 bytes
 240  * are used to handle the calling standard which generally requires pushing
 241  * addresses or registers onto the stack. We should be able to get away with
 242  * less if this becomes important.
