Cannot connect after previous connection failure

[mathieumallet]

Steps to reproduce:

1. Run profiler_gui
2. Attempt to connect to a non-running application -- the 'Cannot connect' dialog is shown
3. Run the application to be profiled
4. Attempt to connect -- the 'Cannot connect' dialog is shown again

Restarting profiler_gui is required to workaround the problem.

I always thought my custom build of the core was broken and profiling would crash my application or something. If this is just a problem in the GUI, that's really good news!

[mathieumallet]

Well it's also possible that both our custom builds are broken in the same way ;)

@yse can you please check and fix it?

I've check fix on linux and macos. Problem was related to unclosed socket on connection failure. Can anybody check it on windows? But I think it's fixed also on windows

Checked on windows - it works.
