Description

At the moment, we hold the lock for 15seconds (default for Java backend, which we inherited from on Android), which obviously will result in ANR on Android. I don't think this happens often when someone is using only Sentry for crash reporting, but when used in conjunction with Crashlytics for example, this can happen pretty easily. But still we could be more conservative here and reduce it to something like Crashlytics (3-4s), this can prevent some of those reported ANRs.
