Write Python in pythonic style instead of translated-from-Perl style, and the 
tables are turned:

$ cat find-rel.py
| import sys
| def main():
|     for fn in sys.argv[1:]:
|         tn = None
|         with open(fn, 'rt') as fd:
|             for line in fd:
|                 if ' is ready' in line:
|                     tn = line.split(' is ready', 1)[0]
|                 elif 'release_req' in line:
|                     print tn
| main()


$ time python find-rel.py *.out
real    0m0.647s
user    0m0.616s
sys    0m0.029s

$ time perl find-rel.pl *.out
real    0m0.935s
user    0m0.910s
sys    0m0.023s

I don't have your log files and my quickly assembled test file doesn't actually 
contain the phrase 'release_req', so my results may be misleading. Perhaps 
you'll try it and post your results?

regards, Anders
