Hi all,

could you please review this small fix for timeout handler?
after  8205687[1], we start to kill a process to get a core dump. since we gather info from the parent process before its children and killing a parent can kill children, we started to observer  suspiciously disappeared children processes (8176214[2], 8217170[3]). the patch changes the order we gather information, so we never kill a process till we gather from all its children. the other part of the patch fixes html-output.
