Subject: [ruby-core:18567] name of "rb_thread_blocking_region()" api

Hi,

Some people pointed out that the name of rb_thread_blocking_region()
 (*1) is wrong function name.

Anyone has better name?


*1:

This function do that:

(1) release GVL (Giant VM Lock)
(2) call passsed function (as func ptr)
    !! In this function, you *CANNOT* use Ruby C APIs.
    !! Ruby C APIs needs GVL on the assumption.
(3) aquire GVL

So you can use this C API to call "blocking process".
See [ruby-core:13893] and following posts for details.
