Under high load, the value returned by `shm_available()` can be total garbage, because it is not multiprocess safe. In the tls module, it makes the tests against the `low_mem_thresholdX` limits randomly return false positives, with errors such as: ``` ERROR: tls [tls_server.c:273]: tls_fix_connection(): tls: ssl bug #1491 workaround: not enough memory for safe operation: 88 ``` although there is plenty of free shm memory. This patch solves the issue by adding a safe version of the function.
