block until a grace period has been detected
Concurrency Kit (libck, -lck)
function will block the caller until a grace period has been detected,
according to the semantics of epoch reclamation. Any objects requiring safe
memory reclamation which are logically deleted are safe for physical deletion
following a call to
ck_epoch_synchronize(3). If you
require that all callbacks be dispatched, then it is suggested that you use
ck_epoch_barrier(3) instead or
follow a call of
This function has no return value.
The object pointed to by .Fa record must have been previously registered via

record = malloc(sizeof *record);
* We are using an epoch section here to guarantee no
* nodes in the stack are deleted while we are dereferencing
* them. This is needed here because there are multiple writers.
* If there was only one thread popping from the this stack,
* then there is no need to ck_epoch_begin/ck_epoch_end.
