/* Stub version of header for fork handling. Mainly to handle pthread_atfork
and friends. Outside dependencies:
UNREGISTER_ATFORK
If defined it must expand to a function call which takes one void*
parameter which is the DSO handle for the DSO which gets unloaded.
The function so called has to remove the atfork handlers registered
by this module. */
/* System specific fork definition. Generic version.
