write_fmt calls write for each formatted field. The default implementation of write_fmt is used, which will call write on not-yet-locked stdout (and write locking after), therefore making print! in multithreaded environment still interleave contents of two separate prints. This patch implements reentrant mutexes, changes stdio handles to use these mutexes and overrides write_fmt to lock the stdio handle for the whole duration of the call.

//! Useful synchronization primitives

|
|
//! This module contains useful safe and unsafe synchronization primitives.
|
|
//! Most of the primitives in this module do not provide any sort of locking
|
|
//! and/or blocking at all, but rather provide the necessary tools to build
|
|
//! other types of concurrent primitives.
