2019-07-18Add experimental `RUBY_SHARED_FIBER_POOL_FREE_STACKS` to control madvise.Samuel Williams
2019-07-18Add note about setting `vm.max_map_count` for Linux.Samuel Williams
2019-07-18Make fiber_pool more conservative on platforms with limited address space.Samuel Williams
We use COROUTINE_LIMITED_ADDRESS_SPACE to select platforms where address space is 32-bits or less. Fiber pool implementation enables more book keeping, and reduces upper limits, in order to minimise address space utilisation.
2019-07-18Add `struct fiber_pool {int free_stacks;}` to control usage of madvise.Samuel Williams
`madvise(free)` and similar operations are good because they avoid swap usage by clearing the dirty bit on memory pages which are mapped but no longer needed. However, there is some performance penalty if there is no memory pressure. Therefore, we do it by default, but it can be avoided.
2019-07-18Add FIBER_POOL_ALLOCATION_FREE to control allocation/free strategy.Samuel Williams
2019-07-18Limit expansion of fiber pool on 32-bit platforms.Samuel Williams
On 32-bit platforms, expanding the fiber pool by a large amount may fail, even if a smaller amount may succeed. We limit the maximum size of a single allocation to maximise the number of fibers that can be allocated. Additionally, we implement the book-keeping required to free allocations when their usage falls to zero.

2019-07-18Implement fiber pool for reduced fiber allocation overhead.Samuel Williams
Replace previous stack cache with fiber pool cache. The fiber pool allocates many stacks in a single memory region. Stack allocation becomes O(log N) and fiber creation is amortized O(1). Around 10x performance improvement was measured in micro-benchmarks.

Build dumped string from base packed data and extended year at once. Although currently ruby_marshal_write_long() never writes more than 5 bytes per its format specification, allocate `sizeof(long)+1` for the sanitation.

If `emesg` is `Qundef`, it is not a message string and then `elen` (the length of the message) is 0. So `emesg` cannot be `Qundef` in the `elen != 0` block. Pointed out by Coverity Scan.
