This one:
http://gcc.gnu.org/ml/gcc-patches/2006-02/msg01762.html
basically it mentiones async I/O as a reason to not do it, but instead the
callee can copy the I/O structure in that case instead (it probably needs
to anyway, as currently those structures live on the stack, so with async
I/O you'd need otherwise to guarantee that the I/O finished before the
current frame is left).
