winthreads should have zero errors, ends up with:
:::Dr.Memory::: ERRORS FOUND:
:::Dr.Memory::: 4 unique, 51 total unaddressable access(es)
:::Dr.Memory::: 3 unique, 9 total uninitialized access(es)
:::Dr.Memory::: 0 unique, 0 total invalid heap argument(s)
:::Dr.Memory::: 0 unique, 0 total warning(s)
:::Dr.Memory::: 1 unique, 1 total, 520 byte(s) of leak(s)
:::Dr.Memory::: 1 unique, 3 total, 72 byte(s) of possible leak(s)

one of the unaddrs is the new thread TEB, b/c I'm missing NtCreateThreadEx
explicit TEB handling. the rest have not been analyzed yet.
the leak is probably issue #248 .
