SSLStream finalizer error #44
Description
I am getting the error below when running a large parallel download with HTTP.jl and OpenSSL.jl. I was using OpenSSL 1.5.0 at the time so I suspect this is the root cause: 74ce7df
error in running finalizer: ErrorException("task switch not allowed from inside gc finalizer")
