Mindharom mentes 10 percenkent fut. A Catalog mentese 11-es, a
masik ketto 10-es prioritassal. Az egyik gondom, hogy sosem
inditja parhuzamosan a ket azonos prioritasu Job-ot. Egy masik
gond, hogy ha a kliens mentese kozben kihuzom a halokabelt a
kliensbol (mikozben mar folyik a mentes, de meg nem fejezodott
be), akkor megall az elet, es soha tobbet semmilyen mentesre nem
hajlando (amig helyre nem all a halozati kapcsolat, de neha meg
utana sem), minden kovetkezo Job-ot eldobal ("marked to be
canceled"), es nem csak annak a kliensnek a Job-jait, hanem
minden Job-ot, tehat semmilyen mentes nincs.

Ha strace-szel megnezem a megfelelo folyamatot, akkor ennyi
latszik:

time(NULL) = 1138012903
nanosleep({197, 0}, NULL) = 0
time(NULL) = 1138013100
time(NULL) = 1138013100
rt_sigaction(SIGUSR2, {0x402437a0, ~[], SA_RESTORER, 0x403a16f8}, NULL, 8) = 0
open("/dev/null", O_RDONLY|O_LARGEFILE) = 13
close(13) = 0
time(NULL) = 1138013100
rt_sigaction(SIGPIPE, {SIG_IGN}, {SIG_IGN}, 8) = 0
send(8, "Q\0\0\0\313INSERT INTO Job (Job,Name,T"..., 204, 0) = 204
rt_sigaction(SIGPIPE, {SIG_IGN}, {SIG_IGN}, 8) = 0
poll([{fd=8, events=POLLIN|POLLERR, revents=POLLIN}], 1, -1) = 1
recv(8, "C\0\0\0\24INSERT 945092 1\0Z\0\0\0\5I", 16384, 0) = 27
rt_sigaction(SIGPIPE, {SIG_IGN}, {SIG_IGN}, 8) = 0
send(8, "Q\0\0\0$SELECT currval(\'Job_Jobid_s"..., 37, 0) = 37
rt_sigaction(SIGPIPE, {SIG_IGN}, {SIG_IGN}, 8) = 0
poll([{fd=8, events=POLLIN|POLLERR, revents=POLLIN}], 1, -1) = 1
recv(8, "T\0\0\0 \0\1currval\0\0\0\0\0\0\0\0\0\0\24\0\10\377\377"..., 16384, 0) = 65
time(NULL) = 1138013100
rt_sigprocmask(SIG_SETMASK, NULL, [RTMIN], 8) = 0
write(5, " _$@\0\0\0\0\250W\f\10\20\267\5\10`W\f\10\0\0\0\200\0\0"..., 148) = 148
rt_sigprocmask(SIG_SETMASK, NULL, [RTMIN], 8) = 0
rt_sigsuspend([] <unfinished ...>
--- SIGRTMIN (Unknown signal 32) @ 0 (0) ---

A kerdeseim:
- Hogyan lehet rabeszelni, hogy parhuzamosan futtasson Job-okat?
- Hogyan lehet rabeszelni, hogy halozati problema eseten ne
alljon le?
