- nsf.c: * enabled MEM_COUNT debugging for multi-threaded apps. We collect the MEM_COUNT statistics now per interp. Therefore, we have to pass around "interp" in case where alloc() and free() or refCount functions are used (textually, a big change) * verified, that nsf runs clean in aolserver/naviserver (all INCR_REF_COUNTS all balanced)
- nsf.c: * refined refcounting debugging * fixed various refcounting bugs, especially in error cases. * added explicit INCR_REF_COUNTs on Tcl_Objs with 0-refCount to ease debugging
