[jira] [Updated] (ARROW-13115) plasma.PlasmaClient do not disconnect when user tried to delete it

["Yuxian Meng (Jira)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/ARROW-13115?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Yuxian Meng updated ARROW-13115:
--------------------------------
    Description: 
```
import pyarrow.plasma as plasma
for _ in range(10000):
    c = plasma.connect("/tmp/plasma")
    del c
```
The above code turns out not to call c.disconnect() automatically, and will cause `Connection to IPC socket failed` error.

  was:
```
import pyarrow.plasma as plasma
c = plasma.connect("/tmp.plasma")
del c
```
