* Fix possible deadlock in 'lock-mutex'.Olivier Dion2022-11-201-9/+10
| | | | | | | | | | | | | | | If we got interrupted while waiting on our condition variable, we unlock the kernel mutex momentarily while executing asynchronous operations before putting us back into the waiting queue. However, we have to retry acquiring the mutex before getting back into the queue, otherwise it's possible that we wait indefinitely since nobody could be the owner for a while. * libguile/threads.c (lock_mutex): Try acquring the mutex after signal interruption.

* Work around unwanted stack retention when using prompts.Ludovic Courtès2022-11-201-5/+12
| | | | | | | | | | Fixes <https://bugs.gnu.org/59021>. Previously, the stack allocated in 'capture_stack' and stored in 'p->stack_bottom' could be retained, leading to heap growth. * libguile/vm.c (capture_stack): Make a single 'scm_gc_malloc' call instead of two.
