Reading /mnt/acme/log reports a log of window create,
put, focus, and delete events, as they happen. It blocks
until the next event is available.
Example log output:
8 new /Users/rsc/foo.go
8 put /Users/rsc/foo.go
8 del /Users/rsc/foo.go
This lets acme-aware programs react to file writes, for example
compiling code, running a test, or updating an import block.
