Hey Emacs, this is -*- outline -*- mode!
* IMPORTANT
** When using descriptor passing, we need to set the fd to blocking before
issueing simple commands, because we are mixing synchronous
commands into potentially asynchronous operations.
** Might want to implement nonblock for w32 native backend! Right now,
we block reading the next line with assuan.
* Before release:
** Figure out if _gpgme_io_pipe should pre-create reader/writer and if we
then can use !start_it in most invocations. Note that gpgme_io_dup
