<H4>Note about HP/UX data libraries:</H4>
<UL>
<LI>HP/UX has a documented characteristic where the shl_unload() function
always unloads a library, regardless of how many times the library has
been loaded. Most operating systems reference-count libraries as they
are opened. In the future (Jitterbug 414) this may be corrected in the
ICU, but at present we work around this problem by simply NOT ever
unloading shared libraries. This means that once a data library
is loaded (ex: libicudata.sl) by a process, it cannot be
unloaded and replaced without stopping and restarting the process.
