// A bit of history here, this used to be --enable-lazy-lock added in
// #14006 which was filed with jemalloc in jemalloc/jemalloc#83 which
// was also reported to MinGW:
//
// http://sourceforge.net/p/mingw-w64/bugs/395/
//
// When updating jemalloc to 4.0, however, it was found that binaries
// would exit with the status code STATUS_RESOURCE_NOT_OWNED indicating
// that a thread was unlocking a mutex it never locked. Disabling this
// "lazy lock" option seems to fix the issue, but it was enabled by
// default for MinGW targets in 13473c7 for jemalloc.
//
// As a result of all that, force disabling lazy lock on Windows, and
// after reading some code it at least *appears* that the initialization
// of mutexes is otherwise ok in jemalloc, so shouldn't cause problems
// hopefully...
//
// tl;dr: make windows behave like other platforms by disabling lazy
// locking, but requires passing an option due to a historical
// default with jemalloc.
