 There is a patch that eliminates the Position uses in CryptoStream. 
 However I'm not sure how it could affect actual working code as I'm 
 not a big user of CryptoStream and current test coverage is weak.
 
 Carlos, can you try the patch with your TLS implementation.

+Hello:
+
+Sorry for the on testing this.
+
+For testing i have used a little test case using the PgSqlClient
+provider in TLS mode against a PostgreSQL DEV server in Fedora core 1
+(mono sources are two days old).
+
+- With the actual CVS version of CryptoStream.cs all runs fine.
+
+- With the patched version (i think i have patched it ok) i got an
+exception, here are the details:
+
