For the benefit of those who may not be as familiar with the config
class, here is some of the related irc discussion:

<zmedico> mgorny: config.setcpv put's the config into per-package state,
and config.reset reverts it to global state
<mgorny> i see
<mgorny> so how does that affect me? ;-D
<zmedico> because yout set self.install_mask in config.setcpv
<zmedico> so you also have to handle global setting of that attribute
<zmedico> every attribute has global and per-package state
<zmedico> for example the usemask attribute is similar
<zmedico> initially it has global use.mask settings
<mgorny> hmm, so you mean i can't rely on both being combined properly
in .setcpv() ?
<mgorny> hmm, but wait, do i need to care about global state at all?
<zmedico> yes, that's what config.reset is for
<zmedico> it transitions back to global state
<mgorny> but is there any case when i need the global state?
<mgorny> i don't think the mask is used without packages
<zmedico> if that's the case, the you can set it to None whien the
config is in global mode
<zmedico> careful though, setcpv returns early in some cases
<zmedico> and you set self.install_mask at the very end of that method
<zmedico> so it's not guaranteed to execute
<zmedico> so you have end up with self.install_mask having the global
setting after a setcpv call
<zmedico> which is fine if there's no package.env setting for that package
