Sebb commented on IO-269:
-------------------------
bq. Marcos indicated that it was not the case in his benchmark.
The readLines() method won't return until it reaches EOF, so when run against a
pre-existing file there won't be any re-opens. It has to be run against a file
that is growing.
bq. Do you have any benchmark to back up the less efficient statement?
Yes, it can be up to about 45% slower.
I used the attached benchmark (to follow), which simulates EOF by reading lines
in chunks.

> The Tailer code works on Windows, except that it locks the file against
> deletion or rename.
> The test code fails to detect this, because it fails to check if the file
> deletion succeeds.
> This seems to be a Windows OS issue.
> A possible solution might be to keep closing and re-opening the file.
