Description

Hi,

I'm getting a race condition here.

Please use a serial queue for setting a user in this array:

```swift
- (void)storeUser:(MXUser *)user
{
[super storeUser:user];

usersToCommit[user.userId] = user;
}
```

Research direction

Locate storeUser: and inspect the existing accesses to usersToCommit, including how the surrounding SDK code handles concurrency. Ensure setting the user is serialized as requested and verify that usersToCommit updates no longer race with other accesses.
