Does the configure line start a daemon running?  If so, try using the
debconf command db_stop before calling it.  

Debconf uses a pipe to communicate with your postinstall script and does
not exit until that pipe is closed.  Since processes get a copy of the
open file descriptors of the parent process when started this can lead
to the daemon holding open the pipe that debconf is waiting to have
closed.
