+Summary: [Regression] IOException in Directory.GetFileSystemEntries
+
+Commit 83191 seems to have caused a regression. Since the beginning of
+August, I'm often getting the following exception:
+
+System.IO.IOException: Win32 IO returned ERROR_GEN_FAILURE. Path:
+/var/www/html/devel.hotfeet.ch/frauchiger/UserData
+  at System.IO.Directory.GetFileSystemEntries (System.String path,
+System.String pattern, FileAttributes mask, FileAttributes attrs) [0x00000] 
+  at System.IO.Directory.GetFiles (System.String path, System.String
+pattern) [0x00000]
+
+...and mod_mono writes this to Apache's errorlog:
+** Message: Unknown errno: Success
+
+My code called Directory.GetFiles(
+"/var/www/html/devel.hotfeet.ch/frauchiger/UserData", "offer_00000_*.*"),
+where the searched directory contains following files:
+
+[js at leonardo UserData]$ ls -l
+total 48

+I'm using Mono from SVN. (And I'm cleaning /tmp/.wapi on httpd restart.)
+
+After reverting commit 83191 (see below), everything seem to work fine again.

+
+	* io-portability.c (_wapi_io_scandir): Special-case patterns
+	ending in '.*' so that files with no extension are also matched.
+	Fixes bug 82212.
+
+	* wapi_glob.h: 
+	* wapi_glob.c: Reinstate WAPI_GLOB_APPEND, and add
+	WAPI_GLOB_UNIQUE to avoid matching the same entry twice when
+	appending.
