Probably better to use sh -c "..."

maybe I do something wrong, but this version fails for me
(and I'm still testing it only on bash):

cn_pec 1 TINFO: timeout per run is 0h 5m 0s
cn_pec 1 TINFO: Test process events connector
cn_pec 1 TINFO: Testing fork event (nevents=10)
cn_pec 1 TBROK: No free filehandle found

I guess there is something wrong free_fd().

Kind regards,
Petr
