here, the spool dir resides under /opt/sge/default/spool, and is
accessible for root (rw), and others (just reading). If I use an:
`QRSH_WRAPPER=env qrsh ps -e f` I get:

14220 ?        S     21:08 /opt/sge/bin/lx24-amd64/sge_execd
32176 ?        S      0:00  \_ sge_shepherd-159019 -bg
32177 ?        Ss     0:00      \_ sshd: me [priv]
32181 ?        S      0:00          \_ sshd: me at notty
32182 ?        Ss     0:00              \_
/opt/sge/utilbin/lx24-amd64/qrsh_starter
/opt/sge-6.0u8/default/spool/node20/active_jobs/159019.1
32184 ?        R      0:00                  \_ ps -e f

meaning it is accessible, didn't it? Without the env wrapper the `ps -e
f` fails as before. Thanks for your help.
