T11627: Improve KIO asynchronicity

meven added a comment. While copying from local to a nfs mount with the destination opened, you get a dolphin freeze because KCoreDirlister is run in main thread and because of #0 statx (fd=-100, path=0x5564ae9e5148 "/media/NFS/Myfile", flags=0, mask=4095,

broulik added a comment. 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.
