The Linux ELF dynamic linker/loader ld-linux.so uses a "lazy" model by default, and defers symbol resolution, shared object resolution to the time when the symbol is first referenced. This sounds like a large latency threat to dynamically linked RT applications running in primary mode. Can this happen, or is this unlikely?
If this is a latency risk, the only solutions I know of are: 1) Statically link all RT applications 2) Invoke all dynamically linked applications with LD_BIND_NOW=1 environment to force the dynamic loader to resolve all symbols at program startup 3) Link dynamic applications with "-z now" GNU ld option to effect same as 2) above. Comments? thanks, Jeff
