Author: kib Date: Sat Nov 29 21:46:28 2008 New Revision: 185456 URL: http://svn.freebsd.org/changeset/base/185456 Log: Unlock the malloc() locks in the child process after fork(). This gives us working malloc in the fork child of the multithreaded process. Although POSIX requires that only async-signal safe functions shall be operable after fork in multithreaded process, not having malloc lower the quality of our implementation.
