trying to get the process id for a spawned process to wait for it

Hi - I'm trying to launch a set number of threads,
wait for them to finish, launch another set of
threads, wait and repeat until there's no more input.
so - I've got this (this is in the middle
of a loop reading a file):
Jobs=$Jobs + 1
/tibcoresources/appmanage.exe <<lots of params>> &
PID=$!
echo $PID is the process
if [[ $Jobs -gt 2 ]]
then
{
echo pausing
wait $PID
Jobs=0
echo starting
}
fi
But - I don't get anything back from $!
so the wait doesn't wait and I end up
launching a bunch of processes and taking
down the server, etc, etc, etc.
What am I doing wrong here?
