01-basic.t has a memory leak, hangs/crashes #1
Description
Doing the blin run for the release, this test ended up consuming enough memory on a 64G box running the raku/blin tests that the OS killed the entire test run.
Running on my local box:

At this point it hangs and memory usage is slowly rising (with some drops, it's not monotonic, but it is trending up) - I left it for several minutes on my personal laptop (mac, 24G) - on the blin machine (ubuntu, 64G), it eventually consumed enough memory to get killed by the OS.
Not surprisingly, it's this test that causes the issue:
# Test loop functions
{
my $count = 0;
my $result = "";
пока(sub { $count < 3 }, sub { $result ~= $count; $count++ });
is $result, "012", 'пока (while) loop works';
}
