in thread capturing command output

Very interesting. ++

I had no idea that perl did that optimization, it is good to know, but it would be nice to have a way to control it.

    but it would be nice to have a way to control it.

    You can already (indirectly) control it — at least in the direction of forcing the use of the shell.  Just add a dummy ";" to the command (which should always be possible without changing the semantics).  Or simply call sh -c "..." yourself.

    (And be sure to add a comment regarding the ";", or else the next maintainer might remove that seemingly superfluous character again... :)
