It seems to be working so far, but with annoying addition to the strace
output:

$ strace true
--- stopped by SIGSTOP ---
--- SIGCONT {si_signo=SIGCONT, si_code=SI_USER, si_pid=4096, si_uid=512} ---
execve("/bin/true", ["true"], [/* 32 vars */]) = 0
exit_group(0)                           = ?
+++ exited with 0 +++

The child process is actually being stopped and continued, but are these
technical details of USE_SEIZE implementation worth seeing?
