Detailed Description

Slab allocator handing out fixed-size blocks for one BIBasis type per instance.

Note

AI-generated documentation. Verify against the source before relying on it.

Allocates MemoryPageSize-byte pages from the system heap and carves each page into TSize-byte cells (typically the size of one VarsListNode or MonomDL etc.). Free cells are threaded into a FreeBlock LIFO so Allocate() / Free(p) are O(1) and avoid hitting malloc on the BIBasis inner loop. ExpandMemory() grabs a fresh page when the free list is empty.
