SquidMan has released uSync 0.1 a small, lightweight mutex/synchronization library written in C. It is meant to be as small and fast as possible. It is used in LibELM for reentrancy support, but was released as a separate library, as it may have other uses.

What's new?

* Fixed a fatal flaw in uSyncRelease that set the data to NULL if we are holding the data.
