26c9b5eaba Speed improvements by removing unnecessary memset() operations. 
Also: do not resize the opcode array of a virtual machine to its
minimum size after code generation completes.  The extra resize
merely uses time. (CVS 4987)

allocations.  But as mem3.c is intended for use in 32-bit embedded
systems, we are not going to change that. (CVS 4978)
