in thread Locking/unlocking program execution using a queue

There is also a problem if the reading script stalls and requests continue to be written, overflowing the FIFO's buffer. Nonetheless it would normally work and if the commands are short a lot of them would fit into 4kB or whatever size the FIFO buffer is.

    No, thats not a problem because every program trying to overflow the FIFO will stall itself and give enough CPU to the stalled script to empty the buffer. The kernel sees to that.
