I've hit this problem while testing juju charms that use ntp
(specifically hbase - bug 800708).

The first instance in the first LXC container start OK; however
subsequent instances in other LXC containers fail as ntp is installed:

root      1157   416  0 14:48 ?        00:00:00 /usr/bin/dpkg --status-fd 49 --configure resolvconf:all openjdk-6-jre-headless:amd
root      1313     1  0 14:48 ?        00:00:00 /usr/sbin/libvirtd -d
root      1398  1157  0 14:48 ?        00:00:00 /bin/sh /var/lib/dpkg/info/ntp.postinst configure
root      1437  1398  0 14:48 ?        00:00:00 /bin/sh /usr/sbin/invoke-rc.d ntp start
root      1453  1437  0 14:48 ?        00:00:00 /bin/sh /etc/init.d/ntp start
root      1458  1453  0 14:48 ?        00:00:00 lockfile-create /var/lock/ntpdate

Running lockfile-create by hand after killing the hanging lockfile-
create:

ubuntu at jamespage-hendrix-hbase-regioncluster-2:~$ lockfile-create /var/lock/ntpdate
*** glibc detected *** lockfile-create: malloc(): memory corruption (fast): 0x000000000105b0e0 ***

[Test Case]
Set a hostname of 64 characters (HOST_NAME_MAX is 64) and create a lock file:

$ lock=/var/lock/lockfile-create-test
$ lockfile-remove $lock
$ sudo hostname hostna01234567890123456789012345678901234567890123456789
$ lockfile-create $lock
