> Remove abstraction that is a holdover from Solaris. Direct usages of `MmapArrayAllocator` have been switched to normal `malloc`. The justification is that none of the code paths are called from signal handlers, so using `mmap` directly does not make sense and is potentially slower than going through `malloc` which can potentially re-use memory without making any system calls. The remaining usages of `ArrayAllocator` and `MallocArrayAllocator` are equivalent.
