This is quite interesting (as I understand, it also should fix "hanged
mplayer process" problem? I have this often, when mplayer crashes there
is another process left behind which hangs until killed manually).
However, it doesn't compile as it is, at least on Fedora 16. When
linking, there is error:

/usr/bin/ld: stream/cache2.o: undefined reference to symbol 'clock_gettime@@GLIBC_2.2.5'
/usr/bin/ld: note: 'clock_gettime@@GLIBC_2.2.5' is defined in DSO /lib64/librt.so.1 so try adding it to the linker command line

Adding -lrt to EXTRALIBS in config.mak fixes it.
