`Text file busy (os error 26)` due to race condition in SVM when doing multiple installations

### Component

Forge

### Have you ensured that all of these are up to date?

- [X] Foundry
- [X] Foundryup

### What version of Foundry are you on?

nightly

### What command(s) is the bug in?

forge build

### Operating System

Linux

### Describe the bug

Our monorepo has a bunch of packages, each using foundry nightly in CI (via `foundry-rs/foundry-toolchain@v1`). Each of these use `forge build` in their build step and we recently tried to turn on parallel builds (via `pnpm`), but it failed with

```
Text file busy (os error 26)
```

The logs weren't specific about where this was coming from, but I later saw a log line that mentioned `solc-0.8.13`:


Unclear if this is a foundry issue or solc issue, but it originates from `forge build`, so I'm starting here.

Ultimately would like to be able to run `forge build` for multiple foundry projects in parallel. Is this an issue with some sort of global cache? Or strictly just a ulimit thing?
