This is the note from chatting with Wizard's Hero K of Proteus-Tech. I derived them to keywords. stdin, stdout, stderr mixin of stdout and stderr PTY ELF mkfifo ( explicit pipe ) stderrred LD_PRELOAD buffer read between user program and varanus/profab/buildbot/fabric buildbot has miss order problem may cause of the buffer read see in buildbot waterfall, the traceback error come before the command that generate it. in c/c++ \r and \n act in different way in linux and window std:flush, std:out printf  :) Have recall my knowledge!!
