The purpose of this page is to catalog Tcl extensions believed to be safe for use in multi-threaded Tcl applications, along with the version numbers in which thread-safety was added. This list might change as the definition of "thread-safe" evolves in the Tcl community.

   * [incr Tcl] 3.2.1
   * [Metakit] 2.4.0
   * [Oratcl] 4.0
   * [tDOM] 0.7.5
   * [XOTcl] 0.9.4
   * [TclBridge] 1.8.1.3848

Here is a list of thread-safe and not-safe libraries, at the bottom of the page.

Well, let me be the first to define "thread-safe":

  thread safe code does not fail with a segfault two times,
  then once with a bus error, then run for a week followed
  by a hardware lockup.
                           -PSE
