Actually I've managed to narrow down my synthetic test, and all I need
is to copy a big file, and it even happens reading and writing to the
SSD (although the stall is less severe).

Just pass a big file as the first argument.

I don't have much memory in this machine, so I guess running out of
memory is the trigger.
