To workaround the multi-line environment variables bug that's still
present in OGE 6.2u8.
(But I ended up using QRSH_WRAPPER for that purpose.)

I'm now doing this:
HOSTS=$( cut -d' ' -f1 $PE_HOSTFILE | fgrep -v $(hostname -s) )
for host in $HOSTS; do
qrsh -inherit -V $host $RUNSCRIPT | grep -q "failed"
# ... react on failure
done
but apparently `execd` does not allow me to qrsh from the prolog:
error: executing task of job 2648607 failed: execution daemon on
host "r01c04b04n02" didn't accept task
anything wrong with my use of `qrsh`?
Thanks,
Riccardo
