On windows, libuv will immediately make a `ReadConsole` call (in the thread pool) when a 'flowing' `uv_tty_t` handle is switched to line-buffered mode. That causes an immediate issue for some users, since libuv can't cancel the `ReadConsole` operation on Windows 8 / Server 2012 and up if the program switches back to raw mode later. But even if this will be fixed in libuv at some point, it's better to avoid the overhead of starting work in the thread pool and immediately cancelling it afther that. See alsov0.10.17-releasef34f1e3
, where the same change is made for the opposite flow, e.g. move `resume()` after `_setRawMode(true)`. Fixes #5927 This is a backport ofdfb0461
(see #5930) to the v0.10 branch.
