Subject: [PATCH] store crash fix
Monero wallet crashes (sometimes) when it is syncing,
while the proper solution (that can be seen in feather)
is to not store wallet while it is being synced, this is not
acceptable for mobile wallets where OS can just come
and kill the wallet because it felt like it.
This patch depends on the background-sync patch, but
to use it as a standalone fix grabbing the definition for the
LOCK_REFRESH macro should be enough.
tobtoht suggested:
_say you want to store every 15 minutes during background sync. you stop the refresh every 15 minutes. then do something like this in the callback:_
```
// Make sure this doesn't run in the refresh thread
onRefreshed() {
if (hasItBeen15MinutesSinceWeStored()) {
store();
}
if (shouldWeContinueRefreshing()) {
startRefresh();
}
}
```
which works for crashes after the wallet is initially synced
but doesn't solve the issue for wallet that are syncing (it
would just wait for it to finish before actually storing).
Also imo store() functin should store the wallet, no matter
the current state.
