Lifetime bounds in as_slice and as_slice_mut in MemMap

The lifetime bounds in the methods `as_slice` and `as_slice_mut` in `types::abs::MemMap` ([link](https://github.com/cogciprocate/ocl/blob/4c4578948c45e0c1c02efd2aa2902b768cae1179/ocl-core/src/types/abs.rs#L752-L760)) are currently ``` #[inline(always)] pub unsafe fn as_slice &'_ [T] { slice::from_raw_parts(self.0, len) } #[inline(always)] pub unsafe fn...

`IoBuf::get_mut_range` unsoundly extends arbitrary lifetime to 'static

This method takes `&self` and returns a `'static` bounded reference. https://github.com/spacejam/sled/blob/69294e59c718289ab3cb6bd03ac3b9e1e072a1e7/src/pagecache/iobuf.rs#L84-L98 This can cause a use-after-free. The following example fails Miri: ```rust use std::{ alloc::{alloc, dealloc, Layout}, sync::Arc, cell::UnsafeCell };...
