My suspicion too. If the x-terminal-emulator puts itself into background,
then the starting terminal ends immediately.

test_script:

  #!/bin/sh
  xterm &

Executed by

  chmod u+x ./test_script
  exec ./test_script

kills the terminal.

(Combining "exec" and "&" in the interactive shell does not kill the
 shell and the terminal:
  exec xterm &
)


What happens if you run

  x-terminal-emulator

without "exec". Does the shell prompt come back immediately ?


Have a nice day :)
