> When running JBossWeb using the native connectors under Windows XP/Win2k3 I'm seeing a Thread Handles leak.  I've traced this with the !htrace feature of CDB (like at http://blogs.technet.com/brad_rutkowski/archive/2007/11/13/got-a-handle-leak-use-htrace-to-help-find-the-leaking-stacks-non-invasively.aspx).  It appears as though this is the behavior reported at https://issues.apache.org/bugzilla/show_bug.cgi?id=42728.  The native stack trace from the leaked handles looks like:
> Handle = 0x00000c64 - OPEN
> Thread ID = 0x00001014, Process ID = 0x00003e44
>  
> 0x2c2d624c: libapr_1!apr_os_thread_current+0x0000003c
> 0x2c339202: LIBEAY32!ERR_remove_state+0x00000062
> 0x7c9011a7: ntdll!LdrInitializeThunk+0x00000029
> 0x7c919213: ntdll!LdrShutdownThread+0x000000ed
> 0x7c80c096: kernel32!ExitThread+0x0000003e
> 0x7c87545b: kernel32!GetConsoleCharType+0x000002a8
> 0x7c80b683: kernel32!GetModuleFileNameA+0x000001b4
> From what I can tell, the end result is that one thread handle leaks per JVM thread that terminates.  Over the course of a long running server application, this becomes a major leak.
