A write +buffer that encounters an error (such as a failed malloc) will clear +its internal state and release any in-use memory, flagging itself as +'not ready'.

Allocation checks perform no +useful service on a general purpose desktop OS where pages are +routinely overallocated and all allocations succeed whether memory is +available or not. The only way to detect an out of memory condition +on the vast majority of OSes is to watch for and capture segmentation +faults.
