Description

- install old osd
- start
- install new package
- try to use a class
-> old osd tries to load new cls_rgw and gets linker error:

2013-07-25 11:13:48.000738 7f4e05c3e700  0 _load_class could not open class /usr/lib/rados-classes/libcls_rgw.so (dlopen failed): /usr/lib/rados-classes/libcls_rgw.so: undefined symbol: _Z21cls_current_subop_numPv

not sure if or how we should fix this. we could load all classes present at startup time?
