 In [changeset:"897d66ad9d77d17dae1b5ac94af792e671a76c13/unix"]:
 {{{
 #!CommitTicketReference repository="unix"
 revision="897d66ad9d77d17dae1b5ac94af792e671a76c13"
 Fix `forkProcess` to inherit caller's `MaskingState`

 ...and while at it, use `bracket` to fix a potential resource leak due
 to `freeStablePtr` not being called if `throwErrnoIfMinus1` throws an
 exception.

 This fixes #8433
