O.k. Sorry for that. Sometimes one doesn't see the most obvious things.
So I should reformulate my problem as follows:
Why does (2) not work (though (1) does)?
# (1)
import sys, signal
class Timeout(Exception):
pass
def alarm_handler(signum, frame):
raise Timeout
try:
signal.signal(signal.SIGALRM, alarm_handler)
signal.alarm(3)
n = 0
while 1:
print n
n = n+1
except Timeout:
print "Time over."

# (2)
import sys, signal, re
class Timeout(Exception):
pass
def alarm_handler(signum, frame):
raise Timeout
try:
signal.signal(signal.SIGALRM, alarm_handler)
signal.alarm(3)
re.search("a(((.)*c)*d)*e", "abcdf"*20)
except Timeout:
print "Time over."
