I have used 2.0-testing for this, with the same dom0 kernel as before -- I 
haven't got round to patching my kernel source tree again yet so that it'll 
work with a newer xen.
This was the output this time:

rt_sigprocmask(SIG_SETMASK, [RTMIN], NULL, 8) = 0
open("/usr/lib/wine/apphelp.dll.so", O_RDONLY) = -1 ENOENT (No such file or 
directory)
open("/usr/lib/wine/apphelp.dll.so", O_RDONLY|O_LARGEFILE) = -1 ENOENT (No 
suchfile or directory)
rt_sigprocmask(SIG_BLOCK, NULL, [RTMIN], 8) = 0
