[...] The problem is that interpreter MUST TEST EVERY operation result that may fail on memory allocation. And it MUST return an error to all higher levels, closing and freeing all allocated resources on the back way.

The existent interpreters either do not test result in most cases (perl), or simply exit(), or in best case they throw exception. Exceptions are easy way to program (you not need to test most operations) and cheap way to test results (for the same reason), but they may lead to socket/file descriptor/etc leak.

I understand the problem, however I think that Lua is still usable.

I'm reading the source code of Lua io library, and any opened file is closed when reached by the gc.

By the way, I'm reading the source code for the NekoVM `file` library, and it *seems* that an opened file object must be explicitly closed, it is not garbage collected.

Moreover, this piece of code (gc_alloc_block function in vm/gc.c) is quite impressive:

#define ASSERT() *(char*)NULL = 0

...

p = malloc(sizeof(gc_page)); if( p == NULL ) ASSERT();

Another unhandled memory error is in vm/context.c:

_context *context_new() { _context *ctx = malloc(sizeof(_context)); pthread_key_create( &ctx->key, NULL ); return ctx; }

So, unless I'm wrong, NekoVM does seems to meets Igor requirements.
