This seems like a bug in xsltproc. A bit of strace shows that it's
full of this stuff:

stat("/usr/lib/libxslt-plugins/nwalsh_com_xslt_ext_com_nwalsh_saxon_UnwrapLinks.so", 0x7fff86f35f40) = -1 ENOENT (No such file or directory)
stat("/usr/lib/libxslt-plugins/nwalsh_com_xslt_ext_com_nwalsh_saxon_UnwrapLinks.so", 0x7fff86f357c0) = -1 ENOENT (No such file or directory)
stat("/usr/lib/libxslt-plugins/nwalsh_com_xslt_ext_com_nwalsh_saxon_UnwrapLinks.so", 0x7fff86f35f40) = -1 ENOENT (No such file or directory)

I didn't let it finish to verify that it's really the time sink, though.
But note that user time is a lot lower than with the SGML toolchain;
it's system time that's the problem (which is suspicious in itself).
