I should mention that lazy symbol resolution could potentially cause
problems in a mutithreaded application since if a symbol is accessed
which was not already accessed, then the run-time linker will execute
code to resolve that symbol.  It may be that the complete application
blocks while the symbol is resolved, or perhaps some threads continue
executing on a different CPU.  Whether this is an issue is
system-dependent.
