bindFailure exception on http client

[gedaiu]

I am making http client requests inside a while(true) loop and after a minute I start getting these exceptions:

Failed to send request to: http://127.0.0.1:6000/test object.Exception@../../../../.dub/packages/vibe-core-1.6.2/vibe-core/source/vibe/core/net.d(223): Failed to connect to 127.0.0.1:6000: bindFailure

I'm wondering whether the HTTPClientResponse objects are fully processed or maybe are left dangling. The callback based version of requestHTTP should clean up the response synchronously, but when using the one that returns a HTTPClientResponse, the caller needs to make sure to fully read or drop the response body.
