Summary: Bug in thread library

Initial Comment:
working with Thread-2.1 under Windows-NT I found the  
following bug. While executing

    for {set i 0} {$i < 1000} {incr i} { 	
	set T [thread::create] 	
	catch "thread::send $T thread::exit"
    }

you can see in Task manager (of windows) that the  
number of handles* grows up.

* under processes in task manager choose columns in  
View menu and mark number of handles.

Greetings,
Villalba

It isn´t a problem of the thread library, but Tcl core. Pay 
attention to the following easy example.

#include <tcl.h>

int ThreadMainProc( int& I ) 
{
	I = 0;
	return 0;
}

int main( void )
{
	int I = 1;
	Tcl_ThreadId* ThreadId = NULL;

	// At this point the number of handles is 14 and of 
threads 1.

	if( Tcl_CreateThread(
			ThreadId, 
			(unsigned int (__stdcall *)(void 
*)) ThreadMainProc,
			&I,
			TCL_THREAD_STACK_DEFAULT,
			TCL_THREAD_NOFLAGS ) != TCL_OK)
	{
		return 1;	// Error handle
	}

	// This loop is finished by the thread.
	// At this point the number of handles is 15 and of 
threads 2.
	while( I )
		printf( "%d", I );

	// At this point the number of handles is 15 and of 
threads 1, i.e. the thread is dead.

	return 0;
}
