bug#38632: 27.0.50; Emacs process name is changed permanently upon creating a named thread

[Ihor Radchenko]

Observed behaviour:

When I try to create a named thread like

(make-thread (lambda () (+ 1 2)) "test-emacs-async")

the emacs process gets renamed to "test-emacs-async" even after the
thread returns. Making another thread with different name renames emacs
process again.

Expected behaviour:

Emacs process name remains unchanged.

Note: by process name, I mean "COMMAND" field in top output. 

Best,
Ihor
