cat 3ae2ab652e system/wayland: sync file at caller specified address
Storing this in sys is incredibly ugly: sys should be stateless and Ops must keep track of their state.

cat 468696f611 internal: beforeExit before reachable fatal calls
These are the only two calls to log.Fatal* reachable during suspended output. Call fmsg.BeforeExit here to catch that.

cat e599b5583d fmsg: implement suspend in writer
This removes the requirement to call fmsg.Exit on every exit path, and enables direct use of the "log" package. However, fmsg.BeforeExit is still encouraged when possible to catch exit on suspended output.
