[Valgrind-developers] valgrind/coregrind

[Tom H. <th...@cy...>]

CVS commit by thughes: 

Implement tcdrain in the pthread library. The fact that this function
is missing was reported in bug #70344 but the reporter then closed the
bug saying that they were using the wrong version of valgrind.

Patch from Henrik Algestam <alg...@ho...>.
