Race condition in older version (0.9.4)

[qishanxiang]

Hi:
   Probably it's a little weird, I wanna report a race condition in an old version pbzip2-0.9.4. The bug is between pbzip2.cpp:704 VS. pbzip2.cpp:966. Basically it would cause unnecessary sleep. The source code is following:

if(OutputBuffer[currBlock].bufsize<1 ||..)
                                                                             <- OutputBuffer[blockNum].bufSize = outSize;
usleep(50000);

This is a pre-release of pbzip2 before 1.0. We are currently at 1.1.6. If there is still a race condition in the latest 1.1.6 we will be happy to look at it, but we are no longer supporting such an older version.
