… pools in parallel

Fix thread instantiation code to create pools in parallel.

When creating a bunch of pools in parallel using Thread,
we need to use a new copy of DmgCommand object because
the command line construction isn't atomic. If we use the
same object, another thread may overwrite the command
line and it could be executed partial (e.g., no pool label).

Add log_step.
