I thought shared libraries eliminated the problems associated with
growing a library, at least by small amounts (like this).

Pixmaps are already shared objects - if you can find out the XID of a
pixmap, you can access it.  The only problem is that when the
allocating client disconnects, the pixmap goes away.  I see at least
two ways to solve this problem:

1) All OL clients are prepared to get BadPixmap errors and check to see
   if the bad pixmap ID is one of the OL glyph substitutes, and if so,
   recreate the pixmap.

2) The glyph substitutes are created via a separate server connection
   whose close-down mode is set to RetainPermanent.
