I executed the same test on my windows pc and macbook, seems on the windows
there's high possibility of failing while on the mac it always pass. It
also seems on windows it is quite slow, after discussion with Mike I think
probably on windows the merging is slower so that more files are kept open,
and thus reaches the limit.

I'll try increase the limit and see how it goes
