SetText hangs indefinitely on Linux

I’m not sure how no-one has noticed this yet, but here it is…

Since #137 was merged, the bashrunner xclip process (when calling SetText) never returns until copying something to the clipboard (e.g. pressing CTRL+C).

This is expected behavior since the xclip -loops option is set to 0 by default and xclip does not close stdout. From the man page:

-l, -loops
        number of X selection requests (pastes into X applications) to wait for before exiting, with a value of 0 (default)
        causing xclip to wait for an unlimited number of requests until another application (possibly another invocation of
        xclip) takes ownership of the selection

The solution seems to be adding -loops 1 to the command, but I’m not sure if this creates other problems… A different solutions is using xsel since it immediately closes stdout after forking.

happy to accept that as a change. but first can u share a failing unit test that illustrates this issue

This is fixed with #345.

Thank you @mcon
