 wasn't really my question. My question was if we want distinct streams =0A=
or if we want want unified stream. Having a unified stream might very well=
 =0Amake sense (and if so we could rename devd to make that more obvious).=
=0A=0AI'm fine with renaming devd to eventd or something else, but Ian was=
 saying that he's worried about the number of notifications that devd has =
to process. =C2=A0I'm not sure that's a real problem at this point, though=
. =C2=A0On freefall, devd used 0.07 seconds of CPU time and has been runni=

of CPU time and it has been up for 5 days and a half. =C2=A0 On my VM that=
 has been up for 5 days and a half, it used 4 seconds of CPU time. =C2=A0R=
enaming sounds like a good idea and it looks like we could leave the optim=

work) was to abstract the devctl kernel code in an API which could make it=
 easy to fan out the notifications to multiple /dev devices. =C2=A0However=
