Adding text to a plot makes R freeze if 'srt' is given a very small 
negative
value, eg:

plot(1, type = "n")
text(1, 1, "some text....", srt = -1e-8)

But if 'srt = -1e-6' (or smaller) or 'srt = -1e-19' (or greater), this 
works.

This seems to be OS-dependent: I observed this under Linux but not 
under Solaris
(I was not able to test under Windows or MacOS).

This looks like a duplicate of PR#9301, which was fixed a couple of 
weeks ago according to this NEWS entry:

    o   Drawing X11 rotated text was buggy for VERY small (negative)
        angle of rotation.  Reported by Ben Bolker.
