If specified, signals occurred in DeleGate processes
will be watched by the parent DeleGate using "ptrace(2)" then recorded
into TRACELOG. If -Tx is specified, DeleGate process which is going
to execute "execve(2)" system call will be trapped and killed. This
will be useful for security enhancement preventing any unexpected
execve() which can be the method of intruders.
This -T option automatically turn on -S option to immediately respond to
events occurred in children, but you can turn off it by adding "s"
flag like "-Ts". Adding "d" flag like "-Txd" will make logging detailed,
while adding "t" flag like "-Txt" will make logging terse.
