Damn. May I ask you to further edit the very same line to 

&FAI::push_command( "mdadm -W --stop $md ; sleep 2 ; cat /proc/mdstat", "$pre_deps_cl", "self_cleared_$md");

i.e., add the wait, change the sleep to a smaller value (to speed things up),
and print /proc/mdstat? I have absolutely no idea why the kernel claims some
device is still busy, and even less so would I know how to figure out what is
still trying to access the device.

Many thanks for your help,
Michael
