Hi,

I wrote a program where many threads access a same uniq zip file.  
Right now, I’m using the Monitor Mixin to ensure the thread safety :

Zip::ZipFile.open(“my\_file.zip”, Zip::ZipFile::CREATE) do |zipfile|  
zipfile.extend(MonitorMixin)  
(…)  
zipfile.synchronize { zipfile.dir.mkdir(…) }  
(…)  
zipfile.synchronize { zipfile.file.open("…") { |f| f.puts … } }  
end

But I feel it’s not necessary to take care of this in my case. Am I  
right ?

Come
