Subject: [ruby-core:40534] Re: [Ruby 1.9 - Feature #3187] Allow dynamic Fiber stack size

Hi,

I agree with this proposal.  Also add same parameter setting feature for
Thread.

However, I can't make good API to specify stack (VM and machine) size
(and other parameters if there are).

There are several proposals.

Type 1: Thread creating argument (ex: Thread.new(stack_size: 1024))
Type 2: Thread global parameter (ex: Thread.stack_size = 1024)

I think Type 2 is not good (to set default value is okay.  However it
conflicts other usage.  Typically thread-unsafe).

I also think Type 1 has also problem.  If you want to pass keyword
argument "stack_size" to fiber or thread, it should be conflict.

My idea is creating new Thread (Fiber) class with new parameter:

  MyThread = Thread.new_template(stack_size: 1024)
  MyThread.new{
    ...
  }

# Of course "new_template" is bad name.

Any ideas?
