Regressions :-(

Tests which did not succeed and are blocking,
including tests which could not be run:
 test-amd64-i386-qemut-rhel6hvm-amd 11 leak-check/check    fail REGR. vs. 14679
 test-amd64-amd64-xl          18 leak-check/check          fail REGR. vs. 14679

Tests which are failing intermittently (not blocking):
 test-amd64-amd64-xl-sedf      9 guest-start                 fail pass in 14756
 test-i386-i386-xl-qemut-winxpsp3 7 windows-install fail in 14756 pass in 14762

Regressions which are regarded as allowable (not blocking):

    libxl: avoid blktap2 deadlock on cleanup
    
    Establishes correct cleanup behavior for blktap devices.  This patch
    implements the release of the backend device before calling for
    the destruction of the userspace component of the blktap device.
    
    Without this patch the kernel xen-blkback driver deadlocks with
    the blktap2 user control plane until the IPC channel is terminated by the
    timeout on the select() call.  This results in a noticeable delay
    in the termination of the guest and causes the blktap minor
    number which had been allocated to be orphaned.

14679[...]

http://www.chiark.greenend.org.uk/~xensrcts/logs/14706/test-amd64-amd64-xl/18.ts-leak-check.log
shows a load of leaked xenstore paths relating to the console. The
bisector has fingered the first one (23428:93e17b0cd035) as having
caused it.

Given that we are at 4.1.4-rc2 unless we can fix this today (or by
tomorrow) we should revert. Possibly we should even just revert and try
again for 4.1.5.

Perhaps we should leave the both the libxl__device_destroy_tapdisk and
xs_rm in libxl__device_destroy? The xs_rm is harmless in the case where 
libxl__device_destroy_tapdisk has done something and useful when it has
not.

The call to libxl__device_destroy_tapdisk in libxl__devices_destroy from
the second patch also looks entirely to me -- the function loops over
devices and yet calls that function only only for the last one (which
happens to be a console). I think this is a mismerge on the backport 
23427:255a0b6a8104 (to unstable) makes this change to
libxl__device_destroy with very similar context to the change to
libxl__devices_destroy in 23427:255a0b6a8104 (to 4.1-testing).
