[Xcb] About next release of xcb/util

[James Cloos]

To give an example of how painful lots of shared libs can be, this is a
comparison of pdfinfo from xpdf vs pdfinfo from poppler.  Both do the
same thing using essentially the same code, but one links only libpaper,
libstdc++, libm and libc, whereas the other links to libpoppler, which
pulls in several other libs:

(I re-ordered the diff to highlight the differences.)

Five extra seconds, an additional page of VM, and a lot more I/O.
