Glenn, I'm not sure exactly where your PDFu class is going wrong, but
in latest code this works as expected using the new Canvas argument

from reportlab.pdfgen.canvas import Canvas
from reportlab.pdfbase.ttfonts import TTFont
from reportlab.pdfbase.pdfmetrics import registerFont, registerFontFamily
registerFont(TTFont('times','times.ttf'),)
registerFont(TTFont('times-bold','timesbd.ttf'),)
registerFont(TTFont('times-italic','timesi.ttf'),)
registerFont(TTFont('times-bolditalic','timesbi.ttf'),)
registerFontFamily('times',
		normal='times',
		bold='times-bold',
		italic='times-italic',
		boldItalic='times-bolditalic',)
sample = 'Hello World'
from reportlab.pdfbase.pdfmetrics import stringWidth
print "stringWidth(%r,'times',12) = %s" % (sample,stringWidth(sample, 'times',12))

canv = Canvas('thello.pdf',initialFontName='times')
print "canv.stringWidth(%r) = %s" % (sample,canv.stringWidth(sample))

canv.drawString(72,72,sample)
canv.save()

this also works exactly as expected using the hacky rl_config stuff

############################################################
from reportlab import rl_config
from reportlab.pdfgen.canvas import Canvas
from reportlab.pdfbase.ttfonts import TTFont
from reportlab.pdfbase.pdfmetrics import registerFont, registerFontFamily
rl_config._SAVED['canvas_basefontname'] = 'times'
rl_config._startUp()
registerFont(TTFont('times','times.ttf'))
registerFont(TTFont('times-bold','timesbd.ttf'))
registerFont(TTFont('times-italic','timesi.ttf'))
registerFont(TTFont('times-bolditalic','timesbi.ttf'))
registerFontFamily('times',
		normal='times',
		bold='times-bold',
		italic='times-italic',
		boldItalic='times-bolditalic')

sample = 'Hello World'
from reportlab.pdfbase.pdfmetrics import stringWidth
print "stringWidth(%r,'times',12) = %s" % (sample,stringWidth(sample, 'times',12))

canv = Canvas('thello1.pdf')
print "canv.stringWidth(%r) = %s" % (sample,canv.stringWidth(sample))

canv.drawString(72,72,sample)
canv.save()

If I add these lines immediately prior to the final for loop in your example

myPDFinit()		
myPDF.register_fonts()
print myPDF.canv._fontname
print myPDF.rlfonts.keys()
for txt in ('012', 'abc', 'ABC'):

then I see this in the output

so perhaps you should consider making the font set up code a bit more transparent
