Subject: [ruby-core:85731] [Ruby trunk Feature#3187] Allow dynamic Fiber	stack size

Issue #3187 has been updated by jjyr (jy j).


How about `Thread.with_configure(stack_size: 1024).new(a: 1, b: 2){}`.
`Thread.with_configure(stack_size: 1024).is_a? Thread::Config`.

 I'd like a way to increase the size of the Fiber stack dynamically so when my program starts, I can set it to whatever value I need for the code I'm running.  4KB is too easy to run into problems when running recursive code but settling on any arbitrary static value seems pointless to me.
