Thank you for the clear explanation!  Now that this is clarified, I
have another question:

For Ruby 1.8, I was able to guarantee the assumption by only using
Ruby's C API inside a POSIX thread:  the thread preserves the C call
stack for the life of the Ruby interpreter.

However, for Ruby 1.9, it is not possible to invoke ruby_init()
inside a POSIX thread (as both you and Nobu have explained in
ruby-core:15759 and ruby-core:15760).

Therefore, how can I guarantee the assumption for Ruby 1.9?


I have one idea, so far, for a possible solution:

1. calloc() a region of memory as a "sandbox" for Ruby.

2. Whenever you want to use Ruby's C API:

2.a. make a backup of the current system stack pointer

2.b. assign the address of the sandbox to the system stack pointer

2.c. execute the desired C function in Ruby's C API

2.d. restore the original system stack pointer

This may not be possible directly, but something along these lines.

Does anyone have other ideas or suggestions?

Thanks for your consideration.
