Re: Perl threads test on Windows: how to close thread handles?

The handles may not be thread handles. They could be event object handles or memory object handles or just about any other type of system handle.

I also see the handle leak. I agree that there is a bug here.

Whatever type of handle they are, without access to them, there is nothing you can do about closing them from user level code.

I think that raising a perlbug incorporating your testcase is called for. Of course, if you could track down what type of handle is leaking first (not easy!), then that would be even better:)

Of course, if you could track down what type of handle is leaking first (not easy!) Actually, it is easy. ;-) The sysinternals nthandle utility will tell you. `perl.exe pid: 3980 4: Thread perl.exe(3980): 5816 8: Thread perl.exe(3980): 3388 c: Thread perl.exe(3980): 3604 10: Thread perl.exe(3980): 4528 14: Thread perl.exe(3980): 1340 18: Thread perl.exe(3980): 3316 ...` [download]	[reply] [d/l]
