Sure, but could you please specify what's wrong with it and/or give me hints as
to how to fix it?  It seems right to me, though I'm pretty new to submitting
patches.  Also, while looking at it, I found a small error in my BlkInfo
caching patch that needs fixing anyhow.  I initially misunderstood how setAttr
works.

if(gcx.infoCache.base is p) {
     gcx.infoCache.attr = mask;
}

should be something like:

if(gcx.infoCache.base is p) {
     gcx.infoCache.attr = mask & oldb;
}
