New submission from itamar <[email protected]>:

Our various logfile implementations don't handle EINTR. As a result, signals that interrupt the writes will cause exceptions to be thrown by the log observer, leading to lost log messages. This is very bad.

I saw this happen due to a SIGCHLD. #733 should fix SIGCHLD-caused issues, but not the general problem, since this can happen with other signals as well.
