I fear you are wasting your wit. Please, convince me that using PIC
is the right thing. I know non-PIC code wastes memory. It makes
administering an selinux system harder. It adds to per-process
startup time.  Unfortunately, a realistic scenario where this
makes xz much more painful to use hasn’t occured to me and I am not
sure how to quantify these effects and weigh them against a running
time difference that is noticeable.
- the text size of liblzma on i386 is only 128 KiB;
- unless I hear some overwhelming reason to, I am not interested in
turning liblzma.so on the i386 into a non-PIC library. I am just
trying to decide whether to link xz to the .a or the .so on i386;
- there is another binary in the same package that links to
If linking to the .so would help with security support or something,
just let me know and I’ll do it.
 These effects are briefly explained in
<http://people.redhat.com/drepper/dsohowto.pdf>, for example.
