This INIT is not *needed*. You need it only if you are working with an
application that turns to be slower on you Mac IIfx or Mac IIci than on a
regular Mac II, Mac IIx or Mac IIcx. In which case, it shows that the
application you are using has a particular way of handling memory (with many
handles) and that the bug of the Memory Manager slows it down.
If your Mac is working OK, don't use it.

This Memory Manager bug is already fixed in the ROM :-)
There are TWO memory manager in the ROMs of the Mac IIfx and Mac IIci, a 24-bit
Memory Manager and a 32-bit Memory-Manager. The bug only exists in the 24-bit
version. Sadly enough, the System 6 can only use the buggy Memory Manager.
However, the long promised and mythical System 7 can use the 32-bit Manager, so
there's no real need for a fix.
