How about reading the release notes of the package?
Stable release 2.4.0 (March 2005) -- CHANGES RELATIVE TO 2.2.0
2.4.0 brings many significant changes and bug fixes.  The most
significant user-visible change is that we no longer supply our own
pthread implementation.  Instead, Valgrind is finally capable of
running the native thread library, either LinuxThreads or NPTL.

This means our libpthread has gone, along with the bugs associated
with it.  Valgrind now supports the kernel's threading syscalls, and
lets you use your standard system libpthread.  As a result:

* There are many fewer system dependencies and strange library-related
  bugs.  There is a small performance improvement, and a large
  stability improvement.

* On the downside, Valgrind can no longer report misuses of the POSIX
  PThreads API.  It also means that Helgrind currently does not work.
  We hope to fix these problems in a future release.

My mistake was to read the online documentation:

It's only when you go to the "top" of the documentation:

that you notice that it is for version 2.2.0 and was last updated 31 August 2004.

Ho hum.
