io-classes-1.6.0.0: strict-stm/README.md

# Strict Software Transaction Memory

The `io-classes:strict-stm` package provides a strict interface to software transaction
memory.  It builds on top of [`io-classes:io-classes`] and thus it provides the interface
for both [`stm`] as well as [`io-sim`].

# Novel testing / space-leak elimination approach

The strict interface provides a novel way of testing/eliminating space-leaks
which might lurk in `stm` shared mutable variables.  Together with the
[`nothunks`] library it was successfully used to eliminate and keep a large
system ([`cardano-node`]) space leak free.
