    I've been seeing consistent hangs with VBox 4.1.18, but mostly
with shared folders and the like under Windows 7 with certain paths
using Cygwin (probably an application issue, but I haven't dug into
why things are that way). I'm not sure what the exact revision is for
9.1-BETA1, but there are a handful of threading and amd64-specific
signal, etc related changes that may or may not affect things.
Thanks!
