Yes, there may be some code which depends on side-effects.
However, I think it is a minor concern and anything which
inherits sockets ought to know to set flags correctly.

Normal Ruby code does not have this problem, since blocking
methods know to call rb_io_wait_*able on EAGAIN/EWOULDBLOCK.

Right.

Should I commit?
