R 2.11.1 version of integrate() restores
concordance with the Fortran routines and correctly diagnoses the
inability of the outer integral to achieve the requested accuracy.
(And, btw, the Q computed above is actually closer to pi/4 than you
will have been getting with the code that "worked well".)

to get a named (atomic) vector by selecting one column of a data frame.
Of course, the vector names must be the rownames of the data frame.
Ok, here is the quiz, I know one quite "cute"/"slick" an
ps://svn.r-project.org/R/trunk/src/library/parallel/R/RngStream.R,
line 45). However, if the intent is to restore the old seed then
this assignment should be made in the global environment, e.g. via
assign(".Random.seed", oldseed, envir = .GlobalEnv)

Have you looked at the current documentation on the svn server?
Yes, that is a lot clearer. Thank you.

What is true is that the line is set before the inline setting of mgp

This is changed in R-patched no
which one (or, at least, I) would expect to place all the tick labels
the same distance into the margin, does not in fact do so.
My interpretation is that axis() is taking mgp[2] rather than the
correct mgp[2]-mgp[3] as the relative position of the tick mark with
respect to the axis line.
J. R.
Axis line is plotted at margin line 1, tick mark labels at line -3.
Is this a bug?
