ast parsing error locations are hard to pinpoint.

sds added the comment:
On a closer observation, I think you are eminently right.
Idle workers take far far far too much RAM.
In fact, I would like to be able to specify that the workers are to be spinned
up on demand only and terminated immediately when they they are done
sds added the comment:
I don't think you need this complexity - just keep the pool max size and submit
jobs only when the loadavg drops below the threshold.
See my implementation attached.

New submission from sds :
The number of workers (max_workers) I want to use often depends on the server
load.
Imagine this scenario: I have 64 CPUs and I need to run 200 processes.
However, others are using the server too, so currently loadavg is 50, thus I
will set `max_workers` to (say) 20

I observe the same behavior on Linux 4.18.0-17-generic #18-Ubuntu
with Python 3.6.7 (default, Oct 22 2018, 11:32:17) [GCC 8.2.0].

thanks for the patch.
alas, I do not build python myself, so I cannot try it.

New submission from sds :
`dbm` errors should contain file names when appropriate, just like `OSError`.
E.g.:
```
>>> open("fo")
Traceback (most recent call last):
File "", line 1, in
FileNotFoundError: [Errno 2] No such file or directory: 'fo'
>&g
sds added the comment:
I think consistency would be nice -- so, yes, `dbm.dumb.error` instead of
`ValueError` (or at least a subtype of `dbm.dumb.error`).
Thanks!

Same problem with 3.6.4, start with
>>> from dbm import gnu as gdbm
then the same incorrect behavior

New submission from sds <s...@gnu.org>:
deleting a key from a read-only gdbm should be gdbm.error, not KeyError:
>>> import gdbm
>>> db = gdbm.open("foo","n") # create new
>>> db["a"] = "b"
>>> db.close()
&g
New submission from sds <s...@gnu.org>:
gdbm offers a function to quickly find number of records: gdbm_count()
http://www.gnu.org/software/gdbm/manual/html_node/Count.html
It would be nice to be able to call it.

New submission from sds <s...@gnu.org>:
After upgrading to gdbm stable 1.14, I get this:
```
>>> import gdbm
Traceback (most recent call last):
File "", line 1, in
ImportError: dlopen(/.../lib/python2.7/lib-dynload/gdbm.so, 2): Symbol not
found: _gdbm_errno
sds added the comment:
the problem is not present in
Python 3.6.2 (default, Jul 17 2017, 16:44:45):
```
>>> import dbm
>>> import dbm.gnu
>>> db = dbm.gnu.open("foo","c")
>>> "a" in db
False
>>> u"a" in
New submission from sds:
`in` and `has_key` have different behavior for Unicode keys for `gdbm` in 2.7:
```
>>> import gdbm
>>> db = gdbm.open("foo.gdbm","c")
>>> db.has_key("a")
0
>>> db.has_key(u"a")
0
>>>
