I'm pretty sure there's a tonne of blocking DBus calls being done all over the place during file copy (checking for slaves on hold, updating kuiserver job tracking info, etc) which can cause apps to hang or slow down if whatever they're trying to call into is busy. Best example: SIGSTOP plasmashell, try copying a file in Dolphin, won't work until plasmashell SIGCONTs.
