Windows: Programs writing to files with ShareMode=0 can't modify the file

[thesolution]

The Tail functionality of the filewatch gem leaves the file being tailed open. This is a problem when a windows program opens a file with dwShareMode=0.
MSDN

I have submitted a pull request that adds a feature to close the file being tail-ed after every read.

The feature is turned on with the env var CloseAfterRead set to "true".

This issue was found when we tried to use LogStash to watch logs on one of our Windows servers.

I have a small VS2012 C++ project that opens the file with an exclusive lock. I can create a repo and link to if it that is helpful.

Any progress on this? I am having a simliar issue where my java apps can't rotate their logfiles since logstash is reading them.

this has been fixed on JRuby, the issue still exists on MRI
