# The patch syscall-security-3 is wrong (provided by me, sorry).
# I missed, that singlestepping_skas() used to reset PT_DTRACE.
# This was handled differently in tt and skas. With syscall-security-3
# applied, a process in SKAS that singlestepped once continues to
# singlestep until the next systemcall occurs, even if it is resumed
# with PTRACE_CONT or PTRACE_SYSCALL.
# This fix unifies the usage of PT_DTRACE in TT and SKAS. PT_DTRACE now
# is set by ptrace(PTRACE_SINGLESTEP,...) and reset by singlestepping()
# and it is evaluated in kern_do_signal().
