rust-chg: remove SIGCHLD handler which won't work in oxidized chg Since pager is managed by the Rust part, the C code doesn't know the pager pid. I could make the Rust part teach the pid to C, but still installing SIGCHLD handler seems horrible idea since we no longer use handcrafted low-level process management functions. Instead, I'm thinking of adding async handler to send SIGPIPE at the exit of the pager.
