The timeout command is only used to ensure a program that hangs does not hang up your process (it's a watchdog timer, see https://commons.apache.org/proper/commons-exec/tutorial.html). If you know kill is going to process (not hang), then the timeout value should be -1. As to how fast this run will depend on your system. If you use jShell with Wait For (see https://www.b4x.com/android/forum/threads/b4x-resumable-subs-sleep-wait-for.78601/#post-498109), you can easily launch several jShell's (even before previous ones are complete) and are only limited by system resources. Each jShell call will start a new shell and then processes your command, both of which will require memory and CPU resources.

Note that a hanging program will not cause your program to hang. A background thread will sit and wait for it to complete.
