srscheck/build colliding with already in progress build

similar to reinhard's script we use a perl script that checks first if
some srs updating routine already runs ...the script is called by cron every 
hour - the problem is that cron jobs are "niced" and we want to give SRS
indexing a high priority ...btw Don, this also might also have slowed down
GenBank indexing...so the trick is to "rsh" the srsupdate command instead of
just calling it by "system" ...bit silly ...but works

first line says "perl5" but Perl4 should also work!

# - redirect STDOUT and STDERR to files
# - move the logfile to /data/update/trace_job
# - move the update file to /data/update/temp
# - control the size of the log file (run file_restriction)
