Work-around for process substitution in mksh

An extremely useful feature of Bash, known as [process substitution](http://tldp.org/LDP/abs/html/process-sub.html) , is missing in the Android shell, [mksh](https://www.mirbsd.org/htman/i386/man1/mksh.htm) . This is highly unfortunate as it prevent you from doing things like: diff <(sort list1) <(sort list2) The mksh site has marked this as a "future plan" [here](https://www.mirbsd.org/mksh.htm#plans) . So my questions is: **Are there any work-arounds for this?** (And what are they?)
