> vfork() is not thread safe and you should not use it. fork() and
vfork() itself is thread safe. The problems arise from using the dynamic linker
from the child that shares (borrowed) the address space and locks from the
parent.
vfork() should be no problem as long as you do not use new (not already linked)
identifiers before you call exec()
.
