Log Message:
-----------
lib: Revert earlier "log write is blocking" handling change
1) It was buggy, because it set O_NONBLOCK rather than removing it.
2) fd flags are shared across all the processes using the fd. We can't
reliably implement the process title update, because some processes are
blocking on the log write() before they change the process title.

Log Message:
-----------
lib: If log write returns EAGAIN, use poll() instead of ioloop for waiting
As explained in 861d40b9aebabccae7d48e49a18cbc631ab1fefe commit message,
ioloop can call various callbacks and it can also recurse back to error
logging. Using poll() directly is safer.

Log Message:
-----------
lib: When log writing keeps returning EAGAIN, change process title only once
Otherwise each call will use up data stack memory.
