For a main thread a thread object is created by the CRT0 before _main gets called so that _main can already run in a generic environment that, e.g., catches stack overflows as a page-fault instead of corrupting the BSS. Additionally dynamic programs have only one CRT0 - the one of the LDSO - which does the initialization for both LDSO and program. ref #989
