Hmm.  How about simply using FIFO's instead,  then one doesn't have any
issues with fork/system/etc

i.e. add options of -serialin <path> -serialout <path> and have -serial <path>
set both of the above.  Then one can simply do:

mkfifo /tmp/serin /tmp/serout
anycmd < /tmp/serout > /tmp/serin &
qemu ... -serialin /tmp/serin -serialout /tmp/serialout
