The initial heap size is governed by a parameter in the boot
blocks. (Is this what HeapFixer changes?)

Files containing INITs (i e those of type "INIT", "RDEV" or "cdev")
can have a "sysz" resource in them, which specifies the minimum
amount of contiguous free space that the code will need. The INIT 31
mechanism will expand the system heap as necessary to fill this need.

Finally, if you're running MultiFinder, the system heap isn't fixed
in size anyway.
