Increasing the limit of maximum open files causes a crash

[sogartar]

Type: Bug

1. Raise the OS max open files limit per process from 1024 to 4096.

ulimit -n 4096

2. Start vscode

code

3. Open any Python file in the editor. Even an empty file will do.
   After several seconds vscode crashes with

The window terminated unexpectedly (reason: 'crashed', code: '133').

Sometimes instead of a crash it freezes.

Note that with a limit of 8192 open files I did not observe the crash.

Output for Python in the Output panel (View→Output, change the drop-down the upper-right of the Output panel to Python)
