Will let you know if it happens often - keep an eye on http://pkg.julialang.org/detail/BufferedStreams.html

Just a note: this failure didn't happen in #21 (https://travis-ci.org/BioJulia/BufferedStreams.jl/jobs/141476500). I need to investigate it later.

0.4 issue was probably spurious, but there's a new one on nightly

22 will fix the problem. I think this is due to a bug of Julia.

[bicycle1885]

I think this issue was resolved in #22.
