This change includes the following updates:
- Added an environment variable `RUBY_TCP_NO_FAST_FALLBACK` to control enabling/disabling fast_fallback
- Updated documentation and man pages
- Revised the implementation of Socket.tcp_fast_fallback= and Socket.tcp_fast_fallback, which previously performed dynamic name resolution of constants and variables. As a result, the following performance improvements were achieved:
(Case of 1000 executions of `TCPSocket.new` to the local host)

This commit adds an environment variable `RUBY_THREAD_TIMESLICE` for
specifying the default thread quantum in milliseconds. You can adjust
this variable to tune throughput, which is especially useful on
multithreaded systems that are mixing CPU bound work and IO bound work.
The default quantum remains 100ms.
[Feature #20861]
Co-Authored-By: John Hawthorn <john@hawthorn.email>
This commit changes RUBY_GC_HEAP_INIT_SIZE_{40,80,160,320,640}_SLOTS to
RUBY_GC_HEAP_{0,1,2,3,4}_INIT_SLOTS. This is easier to use because the
user does not need to determine the slot sizes (which can vary between
32 and 64 bit systems). They now just use the heap names
(`GC.stat_heap.keys`).
The old RUBY_GC_HEAP_INIT_SLOTS isn't really usable anymore as
it initalize all the pools by the same factor, but it's unlikely
that pools will need similar sizes.
In production our 40B pool is 5 to 6 times bigger than our 80B pool.
* bundle gem previously ignored gem.test when passed empty -t flag,
defaulting to RSpec
* bundle gem will now ask user for test framework when passed empty -t
flag and gem.test is set to false, but will not overwrite gem.test
* thor option parsing for String types falls back to human name for nil,
so setting lazy_default to nil won't work
* c5161501e0/lib/thor/parser/options.rb (L224)
Default to Bundler.settings["gem.test"] for empty --test
Add shared examples for test framework to newgem spec
Add examples for empty --test flag to newgem spec
Simplify conditional for prompting test framework
Follow naming conventions for bundler settings
Add more descriptive test framework help text for bundle gem
Update man pages for bundler
