Previously, the memory allocator on Plan 9 did not free memory properly. It was only able to free the last allocated block. This change implements a variant of the Kernighan & Ritchie memory allocator with coalescing and splitting. The most notable differences are: - no header is prefixing the allocated blocks, since the size is always specified when calling sysFree, - the free list is nil-terminated instead of circular. Fixes #9736. Fixes #9803. Fixes #9952. Change-Id: I00d533714e4144a0012f69820d31cbb0253031a3 Reviewed-on: https://go-review.googlesource.com/5524Reviewed-by:
