All cygwin threads have separate context in an object of class _cygtls.  The
storage for this object is kept on the stack in the bottom CYGTLS_PADSIZE
bytes.  Each thread references the storage via the Thread Environment Block
(aka Thread Information Block), which Windows maintains for each user thread
in the system, with the address in the FS segment register.  The memory
is laid out as in the NT_TIB structure from <w32api/winnt.h>:

全ての cygwin スレッドは class _cygtls のオブジェクト中に別個のコンテキストを持っています。

Registration to "methods" is done by "msgpack_rpc_add_method_handler" in "build/src/nvim/auto/api/private/dispatch_wrappers.nenerated.h" that generated by "src/nvim/generators/gen_api_dispatch.lua".

"receive_msgpack" is passed to "rstream_start" as "read_cb" in "rpc_start".
