I hadn't thought about it. Draft it, send it in, I'll see what I can  
do next week.

Pinholes will continue to exist for 370 (aka the next release), i.e.,  
in May. They are likely to exist for the August release, too. Next  
year? Last I heard global warming will melt everything by 2008,  
including drscheme and the assembled gurus, so hukairs :]

P.S. I promised and I will widen the domains for image.ss next week.
