Imap client with ~7500 imap cmds ~250/~500 read() syscall

[Marc Roos]

Looks like this mail client has problems with the archive namespace[1], 
I assume I have nothing strange in there because other clients just 
issue around ~50 cmds. So I guess this is just bad programming of some 
new flashy trendy tool someone has downloaded?

The raw in log has 
    nr
  34212 LIST ""
  35190 SELECT Archive

Like this:

350 SELECT Archive
2351 LIST "" "*"
2352 SELECT Archive
2353 LIST "" "*"
2354 SELECT Archive
2355 LIST "" "*"
2356 SELECT Archive
