According to gdb, fd 11 is closed by zclose(subsh_close) in
execcmd()

and fd 13 by closedumps() (the missing link to compinit?).

(gdb) p *dumps
$2 = {next = 0x0, dev = 64768, ino = 66808, fd = 13, map = 0x7f0d4e833000, addr = 0x7f0d4e833000, len = 125304, count = 1,
  filename = 0x13ae650 "/usr/share/zsh/functions/Completion/Base.zwc"}

It sounds like those fd are closed too many times. I don't have
much time to investigate any further.

Cheers,
Stephane
