Comment #12 on issue 317 by ale...@feldgendler.ru: Util.XSelection.putSelection repeatable hang http://code.google.com/p/xmonad/issues/detail?id=317 I tried running "sleep 5; xclock" and opening a prompt while sleeping. The xclock window didn't appear on the screen until after the prompt was dismissed, but otherwise it went OK and didn't freeze the prompt. On the other hand, during the hang (with the forkOS fix applied), I can see that the process is in a tight loop, busy reading endless events from the X socket. What could these be about? -- You received this message because you are listed in the owner or CC fields of this issue, or because you starred this issue.
