cargo lambda watch hangs with default --concurrency or --concurrency 1 #926
Description
Hello
After updating to v1.9.0 the cargo lambda watch seems to hang at request stack increased function_name when run with the default or 1 concurrency.

When starting with at least 2 concurrency, it executes as expected
