I applied this patch to my branch, to see what would happen. On my
system (x86-64 Fedora 18, with glibc debuginfo installed), I see this
backtrace in the log:
python gdb.execute("attach 11985"); gdb.execute("where")
0x0000003e422bb4e0 in __nanosleep_nocancel () at ../sysdeps/unix/syscall-template.S:81

#5 0x00000000004005fb in main () at ../../../archer/gdb/testsuite/gdb.python/py-sync-interp.c:45
This yielded a FAIL:
FAIL: gdb.python/py-sync-interp.exp: attach and where (pattern 1)
