vfork() is still faster than fork() especially when the parent
process uses big memory.
ruby -rbenchmark -e 'a = "a" * 1_000_000_000; puts Benchmark.measure { system("true") }'
fork: 0.000000 0.010000 0.010000 ( 0.014968)
vfork: 0.000000 0.000000 0.000000 ( 0.000912)

* ext/zlib/zlib.c (gzfile_reset): preserve ZSTREAM_FLAG_GZFILE
[Bug #10101]
* test/zlib/test_zlib.rb (test_rewind): test each_byte
We must preserve the ZSTREAM_FLAG_GZFILE flag to prevent
zstream_detach_buffer from:
a) returning Qnil and breaking out of the `each_byte' loop
b) yielding a large string to each_byte
Note: the test case in bug report takes a long time. I found this
bug because I noticed the massive time descrepancy between
`each_byte' and `readbyte' loop before this patch. With this patch,
`each_byte' and `readbyte' both take very long.

The dynamic sym passed to rb_sym2id may be a garbage object
(as accounted for by dsymbol_check). This fixes an occasional
segfault in "make test-all" for me.
No need to backport, this is from the new symbol GC feature.
