Problem

As of recently (probably #2613), ./build test is failing on Mono for me with this:

1) Failed : Tests.Core.ModuleInstaller.ModuleManagerInstancesAreDecoupled
  Expected: No Exception to be thrown
  But was:  <System.InvalidOperationException: object_op ---> System.IO.IOException: The configured user limit (128) on the number of inotify instances has been reached.

Cause

All of these tests instantiate a NetFileCache or NetModuleCache member variable in a setup step, and in the teardown step they just delete the cache directory. For example:

CKAN/Tests/NetKAN/Sources/Curse/CurseApiTests.cs

Lines 18 to 32 in f98b9f0

[OneTimeSetUp]
public void TestFixtureSetup()
{
_cachePath = Path.Combine(Path.GetTempPath(), "CKAN", Guid.NewGuid().ToString("N"));
Directory.CreateDirectory(_cachePath);
_cache = new NetFileCache(_cachePath);
}
[OneTimeTearDown]
public void TestFixtureTearDown()
{
Directory.Delete(_cachePath, recursive: true);
}

However, this is not enough to clean up after a cache object. NetFileCache inherits from IDisposable and uses its Dispose method to dispose the FileSystemWatcher object that is mentioned so many times in the above errors:

CKAN/Core/Net/NetFileCache.cs

Lines 79 to 92 in f98b9f0

/// <summary>
/// Releases all resource used by the <see cref="CKAN.NetFileCache"/> object.
/// </summary>
/// <remarks>Call <see cref="Dispose"/> when you are finished using the <see cref="CKAN.NetFileCache"/>. The
/// <see cref="Dispose"/> method leaves the <see cref="CKAN.NetFileCache"/> in an unusable state. After calling
/// <see cref="Dispose"/>, you must release all references to the <see cref="CKAN.NetFileCache"/> so the garbage
/// collector can reclaim the memory that the <see cref="CKAN.NetFileCache"/> was occupying.</remarks>
public void Dispose()
{
// All we really need to do is clear our FileSystemWatcher.
// We disable its event raising capabilities first for good measure.
watcher.EnableRaisingEvents = false;
watcher.Dispose();
}

Apparently we finally have enough cache objects being created to run into problems with not disposing them.

Changes

Now we dispose the cache objects we create for tests in the teardown functions. This fixes the above errors for me.

Interestingly, it isn't failing for me.

Yeah, Travis wasn't having problems with it either somehow. Maybe there's a system setting that affects that limit, who knows.
