If MySQL logs to a named pipe, and "no one is there to hear it," does

It could. mkfifo creates blocking named pipes. Meaning a reader will
block, and wait for someone else to start writing to it. Also
vice-versa, the writer will wait for a reader.

A blocking log file sounds really bad to me.
How bad, and why?
Is this an acceptable solution for a development machine where
convenience is more important than performance? Is there a better way
to do this?
