ssl errors

[yannick]

not sure if this is a bug:

when i do lots of requests to aws endpoints, from time to i get an

SSL_read was unsuccessful with ret 0

if i retry, it all works fine.

to handly this nicely in higher level libraries it would be nice if
https://github.com/rejectedsoftware/vibe.d/blob/master/source/vibe/stream/openssl.d#L257
would throw something more specific.

This is a high-level protocol issue, the reader is failing to call leastSize or waitForData before reading. Unless the connection is closed with incomplete data? Are you using the AWS library when getting this error? Can you post a stack trace?
