pub unsafe static mut GC_max_retries: GC_wordExpand description
The maximum number of collections attempted before reporting out of
memory after heap expansion fails. Initially 0. The setter and
getter are unsynchronized, so GC_call_with_alloc_lock()
(GC_call_with_reader_lock() in case of the getter) is required to
avoid data race (if the value is modified after the collector is put
into the multi-threaded mode).
