> And it looks like 8192 is the maximum allowed length for an environment
variable in Windows (http://support.microsoft.com/kb/830473), so we don't
have to do any additional checks.
If I understand the warning correctly, `EnvVarUpdate` will always do the
wrong thing when the limit is reached, no matter what the limit is (and
apparently, 2k would have been enough for earlier versions of windows).
So you've got a workaround that makes the bug less likely to appear, but
no fix yet. I still recommend doing the check, if at all possible, to
ensure that, at worst, PATH isn't meddled with if the limit is reached,
but not emptied.
