; Context switching. We maintain tables specifying which lomem to switch. Each table
; entry contains a word length (l) followed by a longword base address (a). Bytes
; a through a+l-1 are saved and restored across context switches. The length must be
; contained in the low 14 bits of the length word. The upper two bits hold a descriptor
; of how the longword is to be interpreted, as follows:
; 00 Longword is the base address of a data to be switched
; 10 Longword is the address of a (4 byte) pointer to data to be switched
; 11 Longword is the address of a (4 byte) handle to data to be switched
; If the 2 bits specify a pointer or handle address and the low 14 bits specify 0 length
; then this means the length should be filled in later using a call to _GetPtrSize or
; _GetHandleSize. The table is terminated by a 0 length word (all 16 bits).
;
; There is one table for color machines, and another for non-color machines, since some
; lomem exists in one but not in the other.
;
; NOTE: We currently have no use for the heap block type switching, so the types and the
; code are conditionalized out to save time and memory.
