[Open-scap] XCCDF with Shell Script Engine

[Przemek Klosowski]

I ran scap-workbench on F16 (default supplied version, 0.6.1), with the 
provided XCCDF file scap-fedora14-xccdf.xml. The scan gets stuck on rule 
2.2.3.5.a (Find files unowned by user) in some weird deadlock where all 
subprocesses are waiting on futexes:

2706  xxxx poll_s Dec15 python /usr/bin/scap-workbench
9148  2706 futex_ Dec19 /usr/libexec/openscap/probe_rpminfo
9153  2706 futex_ Dec19 /usr/libexec/openscap/probe_textfilecontent54
9161  2706 futex_ Dec19 /usr/libexec/openscap/probe_file

[root at localhost pam.d]# strace -p 2706
restart_syscall(<... resuming interrupted call ...>^C <unfinished ...>

[root at localhost pam.d]# strace -p 9148
futex(0xb70bbba8, FUTEX_WAIT, 9150, NULL^C <unfinished ...>

[root at localhost pam.d]# strace -p 9153
futex(0xb7043ba8, FUTEX_WAIT, 9155, NULL^C <unfinished ...>

[root at localhost pam.d]# strace -p 9161
futex(0xb70b8ba8, FUTEX_WAIT, 9163, NULL^C <unfinished ...>

I tried attaching the debugger to see where it's stuck, but it just says 
it is in the middle of the Python interpreter---is there a way to find 
out what python code is being executed?
