PAGE_SIZE =

The size of one page of memory for a mmap()-ed MemoryPage region. Typically 4096 bytes under Linux.

SIZET2NUM(page_size)
SLOT_SIZE =

The size (in bytes) of a slot in a MemoryPage object. This is the size of a word on single CPU systems and the size of the L1 cache line size if detectable.

Defaults to 128 bytes if undetectable.

SIZET2NUM(slot_size)
SLOTS = 
SIZET2NUM(page_size / slot_size)
SLOT_MAX =

The maximum value a slot counter can hold

ULONG2NUM((unsigned long)-1)
