This is a two button mouse?  With "emulate third button" enabled?
In this case the behaviour is by design and cannot be changed.

To summarize: It's assumed to have been an click with the third
button when you press the two physically existent buttons
together.  As we all know, there's no such thing as "at the same
time".  To allow for jitter (humans are slow), the computer has
to wait after seeing one down event for 1) the other button to
come down or the pressed button to go up, 2) the mouse to move
without other button events, or 3) a timeout without any of the
button or motion events to happen.  I don't know how long you
have to wait between clicking and moving, but your timeout seems
to be rather long.  Wait a little longer and the computer will
see by itself that it was just a single button press. :)

As stated:  this is by design and cannot be changed.  See it as
similar to the ESC key pressing in terminals (you don't know if
it was just ESC or the start of a long sequence like function or
cursor keys, so you have to wait what comes next or for a timeout
to run into).

All you may be able to do is to adjust the three button emulation
timeout.  Or even better -- plug in a pointing device with more
than two buttons, X11 has had a real use for these buttons for
several decades and you will even miss functionality with only
two of them.  The three button emulation is just a hack.

This has been reported in this list.  It's just that some
processes start before the (OS internal) clock is set.  That's
why the start time is "the epoch".  There was even a patch flying
around which solved the problem (adjusted or corrected / set the
start time information the first time the parameter gets listed
and the clock has been set).  Since it was a one liner it might
have been committed already.

It looks like it.  Does your -STABLE version know about UFS2?
Have you tried to "mount -o ro" the -CURRENT partitions to see
if the rw mount has problems with updating (i.e. writing to)
file systems it cannot handle?
