Thanks...Instead of changing the ust release, I could try retrograding
lttng-tools to its last compatible commit.  Which would that be?

I guess what I really need to know is what is the most recent *coherent* set of
commits from git.dorsal.polymtl.ca and git.lttng.org?

On a somewhat related topic, I've found that the git.dorsal.polymtl.ca
lttng-agent (2011-03-23) is broken since 2011-02-25.  It relies on
ustctl_force_switch(pid_t pid), which appeared with the 2011-01-31 ust 0.11-0.12
commit ("Rename libustcmd to libustctl") --- this function was called
ustcmd_force_switch before then.  But on the 2011-02-25 ust 0.11-0.12 commit
("libustctl: use direct socket communication"), ustctl_force_switch(pid_t pid)
changed its signature to ustctl_force_switch(int sock, const char *trace).
