byte[] buffer = new byte[32];
string testFilePath = gzTestFile("GZTestDocument.pdf.gz");
using (var readStream = await ManualSyncMemoryStream.GetStreamFromFileAsync(testFilePath, false, true))

try
{
task = unzip.ReadAsync(buffer, 0, 32);
Assert.True(readStream.ReadHit);
Assert.Throws<InvalidOperationException>(() => { unzip.ReadAsync(buffer, 0, 32); }); // "overlapping read"
}
finally
