* fix `DecrementSizeGuard::drop()` only waking one `Waiter` regardless of whether that waiter was already woken * fix connect-backoff loop giving up the size guard * don't cut in line to open a new connection * have tasks waiting on `acquire()` wake periodically to check if there's a connection in the queue Signed-off-by: Austin Bonander <austin@launchbadge.com>

Tested and this does fix the issues I am seeing on |

Can this be released as SQLx 0.5.2? We just had our SQLx DB pool get stuck without any connections to give out yesterday, hoping this will ensure that doesn't happen again. |

Yes. Planning to do that later today (merge in anything non-breaking and put out a 0.5.2). |
