Hello,

I have submit a bug on "https://bugzilla.xamarin.com/show_bug.cgi?id=11458"
But nobody answer me :( 

I have submit another bug
"https://bugzilla.xamarin.com/show_bug.cgi?id=13884". I think this is the
same problem.

Is nobody use ReaderWriterLockSlim with the same problem.
I hobe someone can help me.


Test-Programm Source Code on bugzilla.xamarin.com
Deadlock if i use Enter/Exit UpgradeableReaderLock from
ReaderWriterLockSlim.

Testet with:
    Microsoft Windows 7 with .NET                 ALL OK
                             Mono 2.10.8          FAIL Deadlock
                             Mono 3.0.6            FAIL Deadlock
                             Mono 3.2.1            FAIL Deadlock

    Ubuntu Server 12.04.2    Mono 3.0.3           FAIL Deadlock
                             Mono 3.0.6           FAIL Deadlock
                             Mono 3.2.1           FAIL Deadlock



Deadlock if i use LockedList implementation. (available in the
test-programm)
with and without UpgradeableReaderLock
Testet with:
    Microsoft Windows 7 with .NET                 ALL OK
                             Mono 2.10.8          FAIL Deadlock
                             Mono 3.0.6           FAIL Deadlock
                             Mono 3.2.1            FAIL Deadlock

    Ubuntu Server 12.04.2    Mono 3.0.3           FAIL Deadlock
                             Mono 3.0.6           FAIL Deadlock
                             Mono 3.2.1           FAIL Deadlock

Testprogram-usage:
    "Netbits.Test.exe use-upgrade" to run UpgradeableReaderLock-Tests
    "Netbits.Test.exe use-lockedlist" to run LockedList-Tests

I hope you can replicate my problems.
